Police said they expect more arrests in connection with what they described as the brutal gang rape of a 15-year-old Bay Area student who struggled with attackers -- some of whom took photos and laughed -- as more than a dozen witnesses passed by and did nothing.

The girl was repeatedly assaulted Saturday night at Richmond High School after she left a homecoming dance early to wait for a ride from her father.

At least seven males beat, raped and eventually robbed the girl in a dark alley behind campus during an ordeal that lasted two to 2 1/2 hours, according to Richmond police. Two people -- 19-year-old former Richmond High student Manuel Ortega and a 15-year-old student at the school -- have been arrested in connection with the assault, authorities said.


Police said the victim was still being assaulted when officers arrived on the scene. The suspects fled as officers found the girl lying in the alley. She was unconscious and naked from the waist up, police said.
