SANTA ANA (CNS) - A suspect in a violent sexual assault of a woman on a bus bench was arrested today as he was exiting work in Irvine, police said.

A woman in her 50s was sitting on a bus bench about 8:30 p.m. Saturday at MacArthur Boulevard and Bristol Street when a man physically attacked her before attempting to sexually assault her at the bus stop, Santa Ana Police Cpl. Anthony Bertagna said.

The suspect, whose name was not immediately available, had dropped his pants just as a bus pulled up, prompting him to flee, Bertagna said.

Police, who had put out surveillance video and a composite sketch of the suspect, received information Wednesday night that led to identifying a suspect, Bertagna said.

The suspect, who was wearing a Dallas Cowboys jersey, did not show a weapon in the attack, Bertagna said.

The victim worked with police to develop a composite sketch of the suspect.
