The officers at Patrol Borough Brooklyn North are transforming their headquarters into a haunted house.

The free event is being held for the second time starting Monday.

All three floors of the Patrol Borough North Headquarters will become a different horrifying scene. Organizers say the haunted house will be both scary and fun.

"It's our way to give back to the community," said Assistant Chief Jeffrey Maddrey. "This is going to be the biggest party in Brooklyn on Halloween.”

The haunted house opens Monday from 5 p.m. to 9 p.m. and runs from 4 p.m. to 9 p.m. on Tuesday.
