OSHAWA -- A local teen suspected of building bombs in his bedroom was charged yesterday in connection with a rigged explosion that injured a student at Donevan Collegiate.
The 17-year-old youth now faces a total of 24 charges under the Criminal Code and under the federal Explosives Act.
Durham Regional Police said a female student suffered minor injuries when a blast showered her with debris last March.
Det. Jim Grimley said a stereo cassette player had been rigged with a tape cassette containing a motion sensor that triggered an explosion when the stereo was moved.
"A teacher went to pick it up off the table and it went off. It was a `directive-type' blast intended to shoot away from the person picking it up", Grimley said.
"Unfortunately, there was a young girl in the area and she was hurt."
Police charged one youth with assault and possession of an explosive device.
A tip prompted detectives to raid the house of another teen on Sunday night.
There they confiscated highly volatile chemicals, detonators, plastic explosives, and detailed instructions on bomb-making.
Grimley said there was enough deadly material in the room to level the Mayfair Ct. townhouse had it exploded.
The teen arrested on Sunday, who cannot be named under the Young Offenders Act, is in custody awaiting a bail hearing on charges including making an explosive, assault, and unlawful use of an explosive device.
