Rats have gotten into the confiscated marijuana at the vermin-infested and decaying New Orleans Police Department headquarters, the city's top cop warned.

"I want you to see the tray of all of the roaches, major rodents on the floor, the cockroaches, the rats eating our marijuana. They're all high," Police Superintendent Anne Kirkpatrick told the Criminal Justice Committee on Monday about the evidence room.

The current department headquarters houses substandard facilities with broken air conditioners and elevators. Officers "have nowhere to use a restroom," according to Kirkpatrick.
