Two Fresno residents were arrested over the weekend on suspicion of sexually assaulting a friend who became unconscious after using marijuana at a Pasadena home.

Police found marijuana, cash and two handguns, Lt. Matt Campeau said.

The victim, a 24-year-old woman from Sanger, reported the assault to police shortly before 2 a.m. on Saturday. Firefighters treated her.

She told police she and her two friends were at a residence in the 600 block of North Madison Avenue. She had marijuana and became unconscious, Campeau said.

When she came to, she was being sexually assaulted, he said. The two suspects, a 24-year-old woman and a 26-year-old man, were arrested on suspicion of oral copulation. The man was also arrested on suspicion of openly carrying an unloaded handgun and possession of marijuana for sale.
