Officials investigate cause of two fires in Southbridge

SOUTHBRIDGE, MA (WHDH) - Investigators are heading back to the scene of a large fire that destroyed a home over the weekend.

The flames closed businesses and left more than a dozen people homeless.

Just hours after that fire, a second one broke out, just blocks away.

According to authorities, the first fire was at 13-15 Central Street and 320 Main Street.

Firefighters rescued a man who had been trapped on the second floor and evacuated apartments.

Four businesses suffered some sort of damage.

A firefighter was treated for smoke inhalation.

No one was hurt.

These fires come two years after a serial arsonist plagued the town.

An investigation into the cause of the fire is under investigation.
