Whitney Houston's daughter was involved in a traffic accident four days before she was found near-death in a bathtub, according to new police records.

Cops in the young star's neighbourhood of Roswell, Georgia say Bobbi Kristina Brown lost control of her Jeep Liberty on 27 January (15) and collided with another vehicle.

Her unnamed passenger and the other car's driver were taken to the hospital, according to the Associated Press.

Brown was hospitalised four days later (31Jan15) after her partner Nick Gordon found her unresponsive and face down in a bathtub at their Roswell home. She was placed in a medically-induced coma and has been fighting for her life ever since.
