1. Zoo previously warned over a security breach as police have announced they are investigating the incident.

As anger grows over the death of Harambe the Gorilla – who was shot after a four-year-old boy fell into his enclosure in Cincinnati Zoo – it has been revealed that the zoo had previously been warned over a security breach in March.

CNN reports that an inspector warned the zoo that the public could have been “at great risk for injury, harm or death” on March 16 when two polar bears went through an open den door into a behind-the-scenes service hallway and wandered down a hallway.

Some visitors were moved for safety as the bears were returned to their main holding area. The animals got through two doors which were left open by keepers and there didn’t appear to be “a formalised method” for double-checking locks and doors.

“Surprising the bears in the keeper area could have resulted in human injury or death.” The report said, adding that if the bears had gotten outside the public would have been at great risk.

The director of the Cincinnati Zoo assured visitors yesterday it was safe.

Thane Maynard said a review is underway to determine any improvements that can make the zoo safer.

The news comes as the prosecutor’s office in Hamilton County announced that police are investigating the circumstances that lead to the gorilla being shot to death.

Spokeswoman Tiffaney Hardey says police are reviewing the matter and continuing to gather information.

“After the review, we will determine if charges need to be brought forward,” Hardy said. ” If it is determined charges need to be brought forward, we would then discuss it with the Hamilton County prosecutor’s office.”

Meanwhile The Washington Post reports that after online trolls targeted the mother of the boy and the preschool where she works police have been forced to intervene.

The mother has been the subject of death threats and racially charged incidents.

“Even though they’re not direct death threats, we’re going to reach out to the mother and let her know what’s going on, if she doesn’t know already,” police spokesman Lt. Steve Saunders  said. “We’re going to keep her in the loop. We’re going to err on the side of safety for her and her family.”

2. Child protection authorities were in “active contact” with family murdered in South Australia.

Child protection authorities had conducted a welfare check at the South Australian property where a mother and her children lived just hours before they were killed.

South Australian woman Adeline Yvette Rigney-Wilson, 29, and her two children, Corey, 5, and Amber, 6, were found dead Monday in a farmhouse at Hillier, north of Adelaide.

Her partner, Steven Graham Peet, 30, has been charged with three counts of murder.

The Advertiser reports that Families SA confirming staff had been in contact with the family.

“Social workers were in active contact with the mother and children,” the agency told The Advertiser. “It would be inappropriate and disrespectful to the deceased to publicly elaborate on the nature of support being provided.

“As with any event of this magnitude, the appropriate authorities will examine the circumstances around the deaths and the department will participate in and support that process fully.”

Adeline Yvette Rigney-Wilson’s mother told The Advertiser that her daughter was caught up “in the wrong crowd.”

“My daughter got mixed up with the wrong kind of crowd, with drugs, ice …

“People are going to judge her based on that and how she looks but I don’t care what they think — she was a beautiful lady who looked after her children and always made sure they were right.” Donna Rigby said.

3. Shark attack victim fighting for his life.

A 29-year-old man is fighting for his life after a shark attack at Falcon Beach in Mandurah on Tuesday afternoon.

Ben Gerring, a fly-in-fly-out worker, was surfing with friends about 4pm when he was mauled by a shark.

WA Today reported that Mandurah Mail deputy editor Nathan Hondros told Radio 6PR that Mr Gerring had lost his legs.

“We’ve got the bloke out of the water, he seems to have lost a leg from above the knee and it looks like ambulance crews are trying to revive him … it’s not looking good.

On Tuesday morning a 3.5 metre great white shark was spotted about 1.8 kilometres off-shore about 4 kilometres south of Falcon reports WA Today.

4. Tanya Plibersek defends Bill Shorten calling Donald Trump ‘barking mad.’

Tanya Plibersek has defended Bill Shorten’s comments on Donald Trump saying Australia’s relationship with the United States would “withstand” a Trump presidency.

Last week, Mr Shorten told a commercial radio station in Darwin that “I think Donald Trump’s views are just barking mad on some issues.”

On 7.30 Ms Plibersek was asked whether Mr Shorten’s comments would diminish the Australia-US alliance should both Labor and Mr Trump be victorious.

“I think our relationship has withstood many years and would withstand a Trump presidency as well” she said .

She continued: “our relationship between our nations is about more than the relationship between the president and the prime minister.”

5. One in six people avoid milk  – based on false medical advice.

A study by Adelaide researchers has found that one in six adults are avoiding dairy products but the vast majority are self-diagnosing.

The CSIRO-Adelaide University study found that people are acting on advice from family and friends, the media, the internet and alternative practitioners under the misguided belief that giving up dairy products will relieve discomfort – such as cramping, bloating or wind – when they don’t need to and are putting themselves at risk of a calcium deficiency.

Study co-author Dr Sinead Golley, a behavioural scientist with CSIRO Food & Nutrition, told News Limited demand seemed greater than the portion of people with genuine lactose or gluten intolerance.

“About one per cent of people are coeliacs, for example, so we were interested in what was driving what appeared to be a large consumption of such products,” she said.

“We found one in six people are avoiding dairy products, but only about a quarter had a formal medical diagnosis to avoid such products — about three quarters were doing it because they had certain symptoms and had decided to self diagnose.

“We found a growing influence of sources outside mainstream medicine influencing their decisions, such as family and friends, the media, the internet and alternative practitioners.

“The avoiders seem to be the product of a growing word-of-mouth phenomenon.”

Study co-author and CSIRO behavioural scientist Bella Yantcheva said people restricting their diet without a medical reason is “very concerning.”

6. Family of dead man vow not to let his fiancé use his sperm.

The family of a man who died after being engaged for a month have vowed to fight any bid by his fiancee to use his sperm.

Tony Deane’s parents Gaye and Phil took their 34-year-old son’s body back to New Zealand last month but before he left his testes were removed by the coroner and stored by Queensland Fertility Group until it is decided whether they can legally be used to fertilise an egg The Courier Mail reports.

The couple had dated for seven months and known each other for eight months.

Ms Patteson told The Courier Mail they first spoke about having a child a week after getting together.

“It would be the greatest honour I could have to carry on such a wonderful man, everything about him that was so special and wonderful,”

But his family has fought the application.

Ms Patteson must now make another legal application asking for the green light to use the stored sperm for in vitro fertilisation.

7. Queen to appear on cover of Vanity Fair.

The Queen will appear as a cover girl for the latest edition of Vanity Fair magazine.

The image was taken by Annie Leibovitz as an additional picture taken when the monarch posed for her official 90th birthday photographs at Easter.

In the image, the Queen is on a rug in the grounds of Windsor Castle with her four pets – two corgis, Willow and Holly, and two ‘dorgis’ Candy and Vulcan.

Photographer Annie Leibovitz, said: “The most moving, important thing about this shoot is that these were all her ideas.”

“She wanted to be photographed with her grandchildren and great-grandchildren; her husband, Prince Philip, the Duke of Edinburgh; her daughter, Anne, the Princess Royal; and her corgis”.

“I was told how relaxed she was at Windsor, and it was really true. You get the sense of how at peace she was with herself, and very much enthralled with her family,” she added.

The Duke of Edinburgh also posed with the Queen for the photographer, and that picture will appear in the magazine alongside the three official images.

8. “Lollipop ladies” told not to wave to motorists.

No waving. Via IStock.

School crossing supervisors have been told by a Melbourne council not to wave to drivers as it may “confuse them.”

The Herald Sun reports Yarra Ranges Council has warned the men and women working on school crossings to be careful about waving to people.

One mother, named Michelle said the crossing supervisor at her child’s school was upset about the orders.

“I’ve got one child at the school and two nephews and they walk home together,” Michelle said.

“They are old enough to walk home together but we rely on the school crossing attendants to keep an eye out for them and make sure they are safe.

“We need these people to be communicating with us.”

She said it was “ridiculous.”

But Council risk and emergency community safety manager Brett Ellis said crossing supervisors were there to ensure safety.

“Council has advised employees that at times some gesturing motions towards drivers could be misleading and to just be aware of this when waving,” Mr Ellis said.
