EAST BOSTON (WHDH) – Crews are working to determine where the fire started at a warehouse in East Boston. The fire broke out just before 6 p.m. Saturday in a warehouse on Border Street, near the shopping center in Central Square.

Firefighters were able to gain access on three sides of the building by cutting open the metal roll up doors, according to a tweet from the department. Once crews were inside, they learned that the building is used to store about 20 empty dumpsters.

One firefighter was treated and transported by Boston EMS with a back injury.

It took teams of firefighters to get the flames under control.

Officials have asked drivers to avoid the area; some roads have been shut down.
