A San Luis Obispo County man is behind bars this morning after allegedly posing as a rideshare app driver and assaulting a passenger. According to a SLO P.D. press release, 29-year-old Angel Munoz Quintana posed as a rideshare driver last weekend when he allegedly sexually assaulted a college-aged woman. An investigation led to a second female victim who was held against her will, but not assaulted. Police believe there may be more victims. Anyone with helpful information regrading this ongoing investigation is asked to contact the SLO P.D.
