Police have laid 37 charges against a Winnipeg teen after uncovering a cache of weapons in a Windsor Park home, including a live explosive device.

Officers responded to a number of related calls last weekend that led them to search a home in the 1000 block of Baudoux Place.

The calls came in on Oct. 12 and 13 and involved property damage to schools and bus shelters, a bomb set off in a dumpster on Dussault Avenue and a vehicle shot up by a pellet gun.

Police laid charges against a 20-year-old man in connection with one of the incidents on Tuesday.

Later that night, officers raided a home on Baudoux Place with the assistance of the bomb unit.

Inside, they found three males, seven pellet guns, brass knuckles and two explosive devices. One had already been detonated and the other was undetonated and live.

The teen is now facing a slew of charges including the intent to cause an explosion, careless use of a firearm and making or possessing explosives. He was also hit with 20 counts of mischief under $5,000.

CBC has learned the teen lives with his mom and brother at the home, and officers had to block off the home for five hours Tuesday night while they searched.

Two nearby homes had to be evacuated.

The teen remains in custody at the Provincial Remand Centre.
