OAKLAND, Calif. — Seven current and former San Francisco Bay Area police officers will be charged in a sexual misconduct scandal involving a teenager who was later arrested in Florida in an unrelated assault case, a prosecutor said.

The wide-ranging scandal surfaced in June when the teenager, who described herself as a prostitute, said she had sex with law enforcement officials in Oakland and elsewhere in the region.

Alameda District Attorney Nancy O’Malley said Friday she was waiting until she’s certain the teen can be returned to California before filing charges against the officers.

The teen was jailed in Florida on suspicion of assaulting a guard at a drug treatment center where she was living.

O’Malley criticized the Richmond Police Department for helping arrange for the teen, now 19, to stay at the center on the other side of the country, saying that her unavailability could hurt the prosecution if she is unable to testify.

The teen has said she had sexual encounters with six Richmond police officers and two dozen other law enforcement officials, including some from Oakland, during the past two years.

Richmond Police Chief Allwyn Brown and department spokesman Lieutenant Felix Tan didn’t return phone calls and e-mails seeking comment.

The teen said she had sex with four officers before she turned 18 and sometimes traded sex for protection from arrest or tips about planned prostitution stings.

O’Malley identified the officers to be charged as former Contra Costa sheriff’s Deputy Ricardo Perez; former Livermore police Officer Dan Black; Oakland police Officers Brian Bunton, Giovani LoVerde, and Warit Utappa; and former Oakland police Officers Tyrell Smith and Leroy Johnson.

The prosecutor said Perez and LoVerde will be charged with having sex with a minor, and Bunton will be charged with felony obstruction of justice and misdemeanor engaging in prostitution.

The other four suspects will face misdemeanor counts of engaging in prostitution and unauthorized access of a confidential criminal justice database, O’Malley said.

Efforts to reach the officers were not immediately successful, and it’s unclear whether any of them are represented by attorneys.

Barry Donelan, president of the union representing Oakland officers, didn’t return a call or respond to an e-mail seeking comment.

The union said in a prepared statement that it was disappointed by the scandal and assured residents the majority of officers are hardworking and upstanding.

The ever-deepening scandal has thrown the Oakland Police Department into crisis and put dozens of officers under suspicion.

The saga began last September when Oakland officer Brendan O’Brien killed himself, leaving behind a suicide note discussing the relationships that he and other officers had with the teen.

In March, a federal judge with oversight of the troubled department said he was dissatisfied with the internal affairs investigation and ordered a reexamination of O’Brien’s suicide.

In June, the teen told the Associated Press and other media outlets that she had sex with four officers when she was younger than 18.

O’Malley said her investigation was limited to Alameda County but authorities had found evidence that the teen had sex with police officers in other jurisdictions in San Francisco, Contra Costa, and San Joaquin counties.
