WATERBURY, Conn. (WTNH) – Two men have died after a fire erupted at a multi-family home on Arch Street in Waterbury early Tuesday morning, according to officials.

Arch Street was closed while fire crews fought the blaze. The fire could be seen coming out of the top floor of the home.

Fire officials confirmed that two adult men died as a result of the fire.

“Crews made an aggressive interior attack into the second floor up into the third floor. At that time, two victims were found,” said Deputy Chief John Perugini, Waterbury Fire Department.

Family members of one victim gathered at the home, searching for answers.

“We had an exposure problem right off the bad, but we were able to put a line on it quickly to save the house next door,” Perugini said.

That wasn’t the only challenge, according to officials. The home is made of an old wood frame and fire officials call it a balloon construction.

“It allows access for fire to travel from floor to floor very quickly. So, a fire that’s on the second floor quickly goes up to the third and up into the attack, and now you have fire all around you,” Perugini said.

The American Red Cross responded to the fire to help those who may have been displaced from their homes.

The cause of the fire remains under investigation.

No other information has been released as of this time.
