A mother's worst nightmare:"The flight attendant ripped the breast pump from my hands."

Australian actress Emilie de Ravin, who has starred in shows Once Upon A Time and Roswell, has detailed how she was assaulted by a female flight attendant while boarding an American Airlines flight in Los Angeles.

Revealing the incident on Twitter, Emilie says she was “grabbed forcefully” by the woman when she attempted to carry a breast pump on board.

“My carry on bag ripped out of my hand…Luckily our pilot was very kind and helpful & apologetic on woman’s behalf & assisted in getting her name & instructions on who to contact to report her,” she wrote.

“However there is NO excuse 4 physical force being used on someone trying to take her breast pump carry on. NOT OK (sic).”

Emilie and her fiancé, Eric Bilitch, welcomed daughter Vera Audrey earlier this year.

Hello world! Thank you for a wonderful first month. Everything is amazing here! Love, Vera

The actress has asked the airline company to dismiss the woman after the incident, with American Airlines sharing they are equally as disturbed by the claims.
