SAN FRANCISCO (AP) -- Authorities in the San Francisco Bay area say they believe it was a hate crime.
Richmond police say about a week and a half ago a woman says she was jumped by four men after she got out of her car.
She says they taunted her for being a lesbian, then repeatedly raped her before leaving her naked outside an abandoned apartment building.
Police in Richmond, Calif., aren't saying why they think the woman was singled out except to say the victim lives openly with her partner, and her car has a rainbow gay pride sticker on it.
A police spokesman says "The level of trauma, physical and emotional, this victim has suffered is extreme."
Richmond police are offering a $10,000 award for information leading to the arrest of the attackers.
