A fire that started in a duplex at 36 Wilton Street on Wednesday, February 4, caused firefighters to evacuate the adjoining (occupied) home at 34 Wilton Street.

The blaze broke out just after 6:30 p.m., according to Princeton police.

Princeton Police and Princeton Fire Departments evacuated three residents of 34 Wilton Street. No one suffered any injuries related to the fire, said police, who also reported that no one was inside 36 Wilton Street at the time of the fire.

Firefighters forced entry into 36 Wilton Street and opened the second floor bedroom walls to extinguish the fire. They also opened the second floor bedroom walls of the 34 Wilton Street.

The investigation revealed that the roof of the duplex had recently been repaired, during which a blow torch was used in the area of the front porch roof. It is thought likely that the blow torch contributed to the cause of the fire, police said.

Subsequent to the investigation the duplex was determined to be uninhabitable, police said.

The Plainsboro Fire Department, Kingston Fire Department, Princeton University Plasma Lab and Princeton First Aid and Rescue Squad assisted at the scene.
