A woman protester at the Occupy Philadelphia encampment at City Hall was raped in a tent, allegedly by a man who had traveled from out of state to join the protest, police said.

The suspect was arrested almost immediately after the alleged attack, and the woman is with the police Special Victims Unit.

The alleged rapist is reported to have been arrested multiple times in connection with a string of armed robberies in Kalamazoo, Mich., officials said.
