A man is now facing several charges after Sarnia investigators determined an explosion on Euphemia Street last month was caused by drug manufacturing activity involving butane.

Police say the explosion happened in a building on April 9 and caused $50,000 in damages. A tenant was injured and was treated and released from hospital.

Levi Dugas, 24, of Sarnia, has been charged with three counts of mischief endangering life, negligence causing bodily harm, mischief over $5,000 and production of a substance.
