Fire officials say an accidental explosion sparked a blaze that injured an 18-year-old man at an apartment complex in southeastern New Hampshire earlier this week.
Fire Chief Keith Hoyle tells Foster's Daily Democrat that the injured teen accidentally caused the explosion that led to Tuesday's fire on Grand Street in Somersworth.
Hoyle says the man was "involved in something in his bedroom" that caused the explosion. No further explanation was provided.
The victim, a high school student, was found outside the apartment building when firefighters responded around 4:40 p.m. He was taken to a hospital in Dover before being flown to Boston for advanced treatment. An update on his condition wasn't available.
The fire caused approximately $75,000 worth of damage.
Police are investigating the incident.
