Police say video taken by a bystander shows a man raping an unconscious, 19-year-old woman behind a trash bin outside a Florida restaurant.

Gainesville police spokesman Ben Tobias says two witnesses separated 34-year-old Christopher Shaw and the intoxicated woman early Thursday. The witnesses told investigators the woman was unable to walk on her own and had difficulty talking and keeping her eyes open.

Police say she told investigators in a hospital interview that she didn't know Shaw and that she tried to push him away but kept losing consciousness. The Associated Press does not generally identify victims of sexual assault.

Shaw was charged with sexual battery and jailed on a $500,000 bond. Jail records did not list an attorney for him Friday.
