A New Zealand father and daughter have been charged with incest for the second time, after it was discovered they had had a second child together.

The pair, from Dunedin, have been told not to associate with each other during their sentences, with the father ordered to stay 100km away from where his daughter lives, Stuff reports.

The 37-year-old father was sentenced to six months community detention and two years intensive supervision, while his 23-year-old daughter was sentenced to two years of intensive supervision.

The pair were first convicted in 2012 after the birth of their first child, and were discovered to again be in a relationship when police were called to a domestic dispute in 2013. Police found an infant which they suspected was fathered by the defendant.

Three months later, the baby was found dead at the mother’s home in what was confirmed to be from sudden infant death syndrome (SIDS).

Reports provided to the court revealed the man justified the relationship by claiming he was a “victim of circumstance”.

The daughter was born after her father entered into a sexual relationship with his foster mother when he was just 13. He had limited contact with his daughter until they were reunited when she was 16 and they started a relationship.

A six-month-old baby boy has been caught up in a terrifying home invasion in Adelaide.

Police are hunting for two masked men who smashed their way into a home in the city’s western suburb of Hendon, where a couple and their young baby were asleep.

The intruders were understood to be armed with a gun and a crowbar before bashing the baby’s father, leaving him with a broken nose. They then fled in the family’s luxury Porsche Cayenne.

The car was found crashed in the gutter in front of the home, with one of the back wheels ripped off.

“I feel sick in the stomach, I’ve got little kids, I could honestly cry for them, they’ve got a baby, it’s just disgusting,” a neighbour told 7 News of the incident.

The search for the men involved continues.

Seven inmates from Malmsbury Youth Justice Centre are still on the run after a riot broke out at the facility just before 3pm yesterday, 9 News reports.

Thirty inmates bashed a guard and stole his access card, before they smashed windows and started a small fire at the facility almost 100km north-west of Melbourne. Some of the youths stole a ute to smash through the perimeter, before carjacking a number of other vehicles to escape.

A white Suzuki was found at an intersection at about 11.40pm last night. The remaining seven youths who are on the run are believed to be travelling in a blue Ford Falcon sedan with the registration ZKV598.

Two of the arrested inmates were found wandering shirtless about 5km from Malmsbury.

Police say the escapees are all aged 16 and 17 and “have significant history with police” and have urged members of the public to avoid them if they are spotted and call Triple Zero (000) instead.

Police are searching for a man, believed to be in his thirties, who indecently assaulted two girls in Arpenteur Park in Baldivis on Tuesday.

Police say the man, believed to have been wearing shorts, a T-shirt and a cap, was walking a “small, scraggy grey-haired dog” when he approached the girls – aged 11 and 12 – before sexually assaulting them and walking away.

“Detectives would like to speak to anyone who was in the vicinity of the park between 11:30am and 12:30pm who may have seen the incident or the man,” a police spokesperson said.

Olympic champion Usain Bolt has been stripped of one of his gold medals from the 2008 Beijing Olympics after one of his teammates, Nesta Carter, was found guilty of a doping violation, ABC News reports.

The runner and the rest of his Jamaican team have been stripped of their 4×100-meter relay gold medal as a result of the findings, meaning Bolt can no-longer call himself a “triple-triple Olympic gold medalist”.

Carter originally tested negative for doping after the race in 2008, but when the I.O.C. re-tested his sample last year it was found to contain a prohibited stimulant, methylhexaneamine.

6. University charged after students left fighting for life when caffeine experiment went horribly wrong.

Northumbria University has been fined after two students were admitted to hospital in 2015 after they were given enough caffeine to make 300 cups of coffee in a university experiment gone wrong.

Alex Rossetto and Luke Parkin were voluntarily taking part in a study to test the effects of caffeine on exercise when a calculation error meant they were given 100 times more than the correct dosage for the experiment, the UK Telegraph reports.

The men were given 30g of caffeine instead of 0.3g. Death had previously been reported after consumption of just 18g of caffeine, Newcastle Crown Court was told.

The university told the court it was “deeply, genuinely sorry” for the error, and was fined £400,000.

Prosecutor Adam Farrer told the court the overdose “could easily have been fatal”.

Both men have since fully recovered from the incident, but Alex Rossetto had reported short-term memory loss.
