(OAKLAND, Calif.) -- Seven Oakland-area police officers have been charged in a sex scandal spanning several East Bay police departments, the Alameda County District Attorney's Office announced Friday.
Prosecutors say they conducted a "meticulous examination" of the massive amount of evidence they gathered for the case, including 2,899 pages of Instagram posts, 76,472 pages of communication on Facebook. 59,960 text messages, 6,069 images, 546 multimedia messages and 21 videos. The investigative team also conducted four separate interviews with the 18-year-old woman at the center of the scandal, said Alameda County District Attorney Nancy O'Malley.
Investigators also consulted with authorities in San Francisco and Contra Costa County where sex acts between some officers and the 18-year-old were alleged to have occurred, O'Malley said.
The following officers were charged in the scandal:
Ricardo Perez, an officer with the Contra Costa County Sheriff's Office, was charged with felony oral copulation with a minor and two counts of misdemeanor engaging in a lewd act in a public place. Perez has resigned from the sheriff's office. The Contra Costa County Sheriff's Office did not immediately respond to ABC News' request for comment.
Dan Black, an officer with the Livermore Police Department, was charged with two counts of misdemeanor engaging in an act of prostitution and two counts of misdemeanor engaging in a lewd act in a public place. Black has resigned from the department. The Livermore Police Department did not immediately respond to ABC News' request for comment.
In addition, five Oakland Police Department officers were charged in the scandal.
Brian Bunton was charged with felony obstruction of justice and misdemeanor engaging in an act of prostitution. Warit Utappa was charged with misdemeanor knowingly and without permission conducting a search of an official criminal justice data and computer systems without an authorized purpose, and Tyrell Smith, who has resigned, was charged with four counts of the same charge.
Leroy Johnson, who has retired, was charged with one count of failure to report, and Giovani LoVerde was charged with felony oral copulation with a minor.
The Oakland Police Department did not immediately respond to ABC News' request for comment. The Alameda County District Attorney's office will not be filing charges against anyone else, O'Malley said.
It was unclear if any of the seven officers charged had obtained a lawyer or entered a plea.
"I do not take lightly the fact that police officers engaged in sexual contact or online sexual communication with a teenaged self-described sex worker," O'Malley said. "This prosecution is holding the wrongdoers accountable."
O'Malley also said that the district attorney's office will do "all it can to ensure that the young [woman] at the center" of the scandal "receives the services and help she deserves."
It has been "widely reported" that the woman went to a rehabilitation center in Florida, O'Malley said, adding that the district attorney's office did not make arrangements for or participate in sending her to Florida and that it "protested her removal from California."
In June, O'Malley announced that an investigation had been launched into the allegations of sexual misconduct. Public outcry followed the news of the sex scandal, she said. The month before, the Oakland Police Department had announced that it had launched an internal investigation into sexual misconduct involving three police officers.
The Oakland Police Department has started dismissal proceedings against the Oakland officers implicated in the case, Oakland Mayor Libby Schaaf said in a press conference Thursday, according to ABC station KGO-TV in San Francisco. Schaaf did note that some of the officers might have previously left the department.
The Oakland Police Officers' Association did not immediately respond to ABC News' request for comment.
The Oakland Police Department has experienced turmoil in the past few months, going through three police chiefs in less than 10 days in June as the news of the sex scandal came to light.
