The sexual misconduct scandal that rocked the Oakland Police Department over the past few weeks has spread to other Bay Area law enforcement agencies, including the latest report that three San Francisco officers allegedly are involved.
The woman at the center of the case, Celeste Guap, 18, of Richmond, spent Tuesday meeting with authorities at the Richmond Police Department, where Chief Allwyn Brown confirmed its investigation of her claims.
"If we find misconduct, we will definitely take the appropriate corrective action," Brown said. "That's what we're committed to doing."
Guap says she's had sex with 28 officers from the Oakland, Richmond and San Francisco police departments, as well as the Contra Costa County Sheriff's Office.
"We are aware of the investigation and are conducting a review to determine if any of our members had any inappropriate contact with the victim," Michael Andrychuk, spokesman for SFPD, told NBC Bay Area.
Guap claims sometimes the sex was in exchange for money and other times in exchange for information related to prostitution sweeps, so that she could avoid arrests. As of Monday, five Oakland officers were placed on leave stemming from her allegations and police Chief Sean Whent suddenly resigned last week, although Mayor Libby Schaaf said his departure was for "personal reasons."
At least one Contra Costa County sheriff's deputy also was placed on leave following claims he had sex with the teen when she was a minor, the department said.
Residents in Oakland gathered to sound off about the scandal and to demand the formation of an independent police commission.
"It's a shame; it's a disgrace," said Carroll Fife of Oakland Alliance. "They need to get out of our city."
Guap also told NBC Bay Area she befriended Whent's wife on Facebook and told her that she was dating an Oakland police officer when she was just 17.
Guap has said she had sex with at least 14 Oakland officers, including three when she was underage; that two officers provided her with confidential police information, including tips on scheduled anti-prostitution stings; and that a retired OPD captain in his 80s paid $250 to have sex with her in a rundown San Pablo Avenue motel.
In April, Guap posted a photo of an Oakland police cruiser in front of a Food Mart with this message: "Took me back to richmond (sic) in style #saucy."
