Spilled butane and an unaware smoker were behind a small explosion that caused minor injuries in St. Thomas.
Police, firefighters, and paramedics were called to the blast at a home on St. Catherines Street last Friday.
Investigators determined one of the residents had spilled butane while refilling a lighter. It was ignited when another resident, who was unaware of the chemical spill, lit a cigarette in the same area.
Minor injuries were reported.
The home did not sustain any major damage, police said.
