BROOKLYN - Police are searching for three people who managed to break into Borough Hall.

According to investigators, the suspects were caught on surveillance camera when they entered through a back door Wednesday night and spent about 30 minutes inside. It's unclear whether or not the door was locked.

The group roamed the hallways and attempted to get onto other floors of the building, but left when they were unable.

A spokesperson for Borough President Marty Markowitz said that nothing appears to have been stolen.
