A multi-family house in Westbrook was damaged by fire Tuesday morning.

The Westbrook Fire Department was called to 181 Brown St. around 7 a.m. for a report of a building fire. Police officers who arrived first at the scene reported heavy smoke coming from the third floor eaves and window.

“There were people in the home, but everybody got out safely,” said Deputy Chief Stephen Sloan.

Chief Andrew Turcotte said firefighters made an aggressive interior attack and brought the fire under control within about 30 minutes.

The fire appeared to start between the floor of the third floor and the ceiling of the second floor, but the cause has not yet been determined, Sloan said.

There were smoke detectors in the building that began sounding once firefighters opened the door to the attic, Sloan said.

The majority of the damage was on the third floor, although there were water and smoke damage throughout the entire building.

Turcotte said one tenant living in the first-floor apartment and two tenants from the second floor unit were home when the fire started. One cat died in the fire and another cat is missing.
