Firefighters responded early Monday morning to a multi-home fire that ripped through the Neptune Park neighborhood in New London.

One home on Mott Avenue was completely destroyed in the blaze that spread to at least five other homes, according to New London Police Chief Thomas Curcio.

Curcio said the house where the fire started was fully engulfed in flames when firefighters arrived on the scene following reports of a house fire. Shortly after, several calls streamed in reporting fires at nearby homes.

“The wind blowing [the fire] started fires on other homes,” said Curcio. “The wine was carrying hot embers to the houses across the street.”

Two homes behind the house were damaged along with at least three to four other homes. City and fire officials had to shut down power to an entire grid in the area as they battled the flames, Curcio said.

One firefighter was injured battling the blaze, suffering an injury to his knee. He was taken by ambulance to Lawrence + Memorial Hospital, Curcio said.

No residents were injured in any of the fires. One man was in one of the homes that caught fire, but he escaped safely, Curcio said.

The people who live in the home where the fire started were not home at the time of the blaze but were headed back to New London this week to celebrate Thanksgiving, Curcio said.

Investigators did not know what caused the fire.

“It’s going to be quite a while to investigate that and figure that out,” said Curcio.

Firefighters and emergency medical responders were on the scene from Groton, Norwich, Poquonnock Bridge and Mohegan Tribe departments, Curcio said.

“It’s going to be an extended multi-day effort,” the chief said.
