A British mom is still suffering through a nightmare that began one year ago on a vacation to the Big Apple – when the city’s child-welfare agency seized her daughters after she took ill, and put into a database information that prevents her from becoming a foster mother.

After Yvonne Bray contracted pneumonia during a Christmas-week shopping trip last year, her teenage daughters were held in a group home for 30 hours by the Administration for Children’s Services, and she was hit with charges of abuse and neglect.

The traumatized schoolgirls – Gemma, 15 and Katie, 13 – said they were strip-searched, asked if they were ever sexually abused or suicidal, and were subsequently split up during the ordeal.

They were given medical examinations and told they could not leave.

Bray, 39, who had just finished a 12-month training course to become a foster mother, was told by British authorities she couldn’t work with any children until her name was removed from the New York State Child Abuse Maltreatment Register.

Bray, who lives about 200 miles west of London, says she’s spent almost the entire year writing letters and even contacting the US Embassy trying to clear her name.

“It’s crazy,” the mom said in a telephone interview.

“Why should I fight to clear my name for an accusation that never should have come about in the first place?”

ACS spokeswoman Sharman Stein said a form letter Bray received from the agency was “generated as a matter of course” after her children were temporarily placed in ACS care.

“The letter is simply informational: Ms. Bray is not under investigation. She never was,” Stein said in a statement. “The letter she receives is simply the way in which our system is legally able to become involved in helping families which are unable to temporarily care for their children.”

However, Bray said she received a copy of a letter that was sent to authorities stating she was the “subject of a report of suspected child abuse or maltreatment” reported to the state.

She is still unsure how her daughters ended up with ACS. She remembers them accompanying her to a Queens hospital and waking up later to realize they were gone. Bray said she had to make a flurry of calls to find out where they were.

She said the girls were traumatized by the experience.

“My youngest one, she slept in my bed for three months after we got back,” Bray said. “They still have issues with it.”

Bray’s Queens lawyer, Peter Lomtevas, says he may file a complaint with the city’s Department of Investigation because ACS is obligated to provide parents with a follow-up letter saying they did not neglect or abuse their child after an investigation. If that doesn’t work he’ll go to court.

The lawyer is not the only one in her corner. A group in Britain has started a Facebook site called “Justice for Yvonne Bray.”

“What I don’t understand,” Bray said, “is why ACS was treating my children like they were being removed from an abusive home.”
