CITY HALL — Four days after the city released a statement calling the latest lawsuit filed against its Police Department “baseless and disingenuous,” Mayor Gary Bric on Tuesday said the FBI was investigating the allegations.

He also announced that the Burbank Police Department was being investigated by the Los Angeles County Sheriff’s Department, which was to turn over its findings to the county district attorney’s office, paving the way for the city to bring in its own outside attorney to review the allegations.

Seven current and former members of the Burbank Police Department have filed lawsuits since May, claiming everything from unfair demotion and retaliation, to sexual harassment and racial discrimination.
