BROOKLYN - Tenants used force to get back into a Brownsville apartment building Tuesday after being locked out. 

Tenant advocacy groups helped change the locks, but the landlord says residents don’t belong there anymore.

According to Cypress Hill Local Development Corporation, a vacate order was issued after a fire, and no one was allowed to live there unless repairs were made. However, residents claim the landlord moved new people in before the order was lifted.

The landlord says he bought the vacant building in an auction and that it's now up to tenants to battle out their previous leases in court.
