The Richmond Police Department started an investigation last week after several officers came forward claiming to having connections with the “young lady at the center of the Oakland police investigation,” Capt. Bisa French said.

The case comes after three Oakland police officers were put on leave and two other officers resigned after they were accused of having sexual relations with a police dispatcher’s underage daughter.
