An Oakland police officer prosecutors had linked to an expansive law enforcement misconduct scandal involving a sexually exploited teenager will not be charged, an official said Thursday.

Alameda County District Attorney Nancy O’Malley said in September that her office would file charges against Officer Warit Uttapa and six other current and former officers and deputy sheriffs for crimes ranging from oral copulation with a minor to obstruction of justice.

The 19-year-old Richmond woman at the center of the scandal — the daughter of an Oakland police dispatcher — told The Chronicle that she had sex with nearly 30 police officers and deputies in the last two years.

The teenager said that a few of the officers paid her, while others tipped her off about prostitution stings or ran the names of people she knew through crime databases.

On Thursday, Deputy District Attorney Sabrina Farrell said that Uttapa, accused of illegally accessing one such database, will not be charged because of insufficient evidence.

The other men O’Malley named at the time have since been charged. In the weeks that followed, Contra Costa County prosecutors accused an 81-year-old retired Oakland captain of paying the young woman for sex, and another Oakland police officer was charged with engaging in prostitution and obstruction of justice in a case involving a different woman.

The scandal prompted an audit of the Oakland Police Department’s hiring practices — nearly all of the men accused had only been on the force for a few years — and led to the departure of Police Chief Sean Whent.
