A drug-related explosion and fire at a town home in a northwest-side neighborhood injured three people, sending one to a hospital Monday, authorities said.
The most seriously hurt person received burns that were not life-threatening, said Capt. Barrett Baker, a Tucson Fire Department spokesman.
Firefighters were dispatched to the 3900 block of North Pomona Road at 1:14 p.m., Baker said.
That's near North Flowing Wells and West Roger roads.
About 20 minutes later, the department's hazardous-materials unit was sent to investigate the cause of the explosion, Baker said.
The explosion occurred as the residents "were trying to extract hash oil from marijuana," said Sgt. Chris Widmer, a Tucson Police Department spokesman. "They were using butane and kitchen items, which caused the explosion and fire."
Two men and a woman were arrested and are facing charges of conspiracy to manufacture a narcotic drug, unlawful possession of a narcotic drug for sale, and unlawful possession of marijuana for sale, Widmer said.
The suspects' names were not released.
