(CBS) LOS ANGELES A former Los Angeles Police Department deputy chief is under investigation for allegedly giving favorable treatment and even promotions to female officers in exchange for sexual favors, officials said Thursday.
The allegations against former Internal Affairs Deputy Chief Michael Berkow were raised in a harassment lawsuit filed in May in Los Angeles Superior Court by Sgt. Ya-May Christle of Arcadia. Berkow is now the police chief in Savannah, Ga.

"We are aware of it and yes, we are investigating," Lt. Paul Vernon of the LAPD's Media Relations Section said. "The allegations alleged in the lawsuit are under investigation. Actually, they have been under investigation for quite some time, but there is really nothing further we can comment on as this is pending litigation.
Asked if there was a relationship between Berkow's leaving the department, Vernon replied, "I don't think so."
Berkow could not be reached for comment.
In an interview with the Los Angeles Times, LAPD Chief William Bratton confirmed the investigation was being conducted, but he called Berkow "an outstanding police officer, hardworking, dedicated."
Christle was hired by the LAPD in February 1989 and was assigned to Internal Affairs in 2003, which was headed by Berkow, according to her lawsuit.
For the next three years, Christle was advised that some female officers who transferred into her unit were Berkow's "special friends" and to "take care of them," the lawsuit stated.
According to the lawsuit, Berkow's office in the Bradbury Building had an air mattress inside and Christle saw several female officers leave there, followed by Berkow wearing a T-shirt and pajamas.
After one female officer who was trained by Christle had sex with Berkow, she was given a pay raise and a coveted position that made her Christle's boss, the lawsuit states.
Berkow also had sexual affairs with a female sergeant and a female captain, also rewarding them with enhanced or extended positions within the department, the lawsuit alleges.
The suit claims that Berkow told Christle to stop pursuing the most serious internal charges against yet another female officer who was arrested
along with her husband for making criminal threats, resisting arrest and providing false information to a police officer.
Berkow also had an affair with the officer, whom he met while she was posing as a prostitute during an undercover police detail, the lawsuit stated.
Christle eventually filed an internal complaint stating Berkow was trying to influence the investigation involving the troubled female officer, according to the lawsuit.

In August 2005, Christle saw a note on a male officer's desk which read, "If you can get Ya-May's computer off her desk, I will give you a week of free lunches," the suit claims.
She later found her computer missing and learned that information was taken from it regarding her investigation into the 1997 fatal shooting of
rapper Christopher "Notorious B.I.G." Wallace, the lawsuit states.
Wallace's family members have alleged two Los Angeles police officers conspired to kill him and Christle was unable to provide them with crucial information they needed because her computer was tampered with, according to the lawsuit.
Christle did not have sex with Berkow and so she did not receive the advancements given the other female officers, the lawsuit stated.

Christle also maintains she was discriminated against because she is Asian-American, the lawsuit stated.
