A big sigh of relief for residents in north end Cartierville.
The Montreal police bomb squad has dismantled explosive devices found at triplex on Robertine-Barry street.
Officers spent the day and night dismantling them, 19 in all.
Firearms were apparently also found.
Police have been questioning an 18-year old man they believe acted on his own and was not part of a group or a gang.
It's not know if he had permits for the weapons.
Some 50 Cartierville residents have been told they return home after being forced out as a result of the long drawn police operation.
The suspect is expected to appear in court Monday on explosives charges.
He might face additional charges.
