FREMONT -- A 20-year-old man is facing felony charges in a hash lab explosion that injured himself and a teenage girl last October.
Ryan Horrigan of Fremont was arrested Wednesday on suspicion of manufacturing illegal drugs and a probation violation more than seven months after the explosion took place at a house near Washington High School.
Horrigan and a teenage girl were hospitalized after they were burned in the Oct. 15 explosion, police spokeswoman Geneva Bosques said.
Fire crews responded about 5:55 p.m. to the home in the 4200 block of Canfield Drive, which police said is known to them for various drug use and probation violations, Bosques said. Within minutes, crews had knocked down the one-alarm fire, found burning in the laundry room of the home.
Police say Horrigan tried to extract hash oil using butane canisters in the closed room, which also houses a water heater. Authorities believe it was the flame from the water heater that ignited the butane gas, sparking the explosion.
Horrigan was taken to a trauma center with severe burns, and the teenage girl was taken to a hospital to be treated for minor burns, Bosque said.
Officers have spent the past several months investigating the case and recently secured a warrant for Horrigan's arrest. Officers located Horrigan at a home in the 6000 block of Joaquin Murrieta Avenue in Newark, where Bosques said Horrigan was taken into custody without incident.
Horrigan, being jailed on $100,000 bail, was set to appear in court to be arraigned on his charges on Monday.
