Britney questioned on baby injury

Britney Spears and her husband have been questioned by child protection officials after their baby suffered a fractured skull.

Investigators in Los Angeles visited Spears and Kevin Federline, 28, after being tipped off by doctors who treated six-month-old Sean for the injury, apparently caused when he fell from his high chair.

The Los Angeles County Sheriff's Department, which accompanied child protection officers on the visit, said the matter was settled at the time.

In February Spears, 24, angered child welfare campaigners when she was pictured driving with Sean in her lap.

She apologised for the incident, claiming she had been pursued by photographers at the time.

Spears married dancer Federline, 27, in September 2004 after they had been together for just six months.

Federline, who is currently in LA on music business, said Sean was "fine" when asked about his son's condition.
