A man injured in an explosion at a Midtown marijuana dispensary last week has been charged with arson and other offences, Toronto police say.

Police and emergency crews were called to Tweeder Medicinal Dispensary at 353 Eglinton Ave. W. for a report of an explosion at around 7:30 p.m. Friday.

Security footage of the blast obtained by CTV Toronto showed a plate glass window shattering, sending glass shards onto the sidewalk and roadway.

The blast came from the building’s basement, fire investigators said over the weekend.

Witnesses said a man with severe burns on his arms and face exited the dispensary after the blast. He also appeared to be missing fingers on one hand.

Police said he was taken to hospital for treatment.

On Wednesday, a 29-year-old suspect identified as David Coleman of Smithville, Ont., was arrested and charged with mischief endangering life, arson with disregard for human life, possession of the proceeds obtained by crime, and various drug-related offences.

Police earlier said Coleman was arrested and charged as part of a widespread crackdown on dispensaries back in May.

The Ontario Fire Marshal’s Office and police continue to investigate.

Anyone with information about this incident is asked to call police at 416-222-8477 (TIPS).
