ENFIELD, Conn. (WTNH) — A house fire at a three-family home temporarily shut down Route 5 in Enfield on Tuesday.

The route was closed between New King Street and Pease Street, but had reopened by 7:30 p.m.

The fire broke out at bout 3 p.m. at 1077 Enfield Street, according to officials. There was heavy fire on the front porch when crews arrived, and one person was still trapped inside.

The female, whose age has not been specified, jumped out of a second-story window and was taken to a local hospital with minor cuts from broken glass.

Witnesses said they heard two explosions.

Nicolas Abraham said he’d just gotten off the school bus when the house, which was across the street from his stop, burst into flames. He said another bus let students off on the corner when the second explosion happened.

“The bus driver was like, ‘Get back in,’ and everyone was pushing and getting back in, so then I got dropped off at Mountain View,” he said.

Later, residents were temporarily allowed back in to get bare essentials. The Red Cross is helping the 12 people who were displaced.

The cause of the fire has not been determined.
