Billy Bob Thornton’s estranged daughter has been freed on bail - two months after the babysitter was arrested for neglecting a child who died in her care.

Amanda Brumfield - Thornton's 29-year-old child from his marriage to first wife Melissa Gatlin - was arrested in May following an incident last October, when one-year-old Olivia Garcia fell from a playpen and hit her head.

The tot's death was ruled a homicide and Brumfield has been charged with a number of crimes, including first-degree murder, aggravated child abuse and aggravated manslaughter.

Brumfield - who has not had any contact with Thornton for several years - was released from Orange County Jail in Florida on Friday after paying $279,000 for her freedom.

She is due to return to court in December when she will stand trial.
