Two Calgary teens have been charged with 15 firearms offences, after police stopped a suspicious vehicle and found a shotgun among other weapons.

At about 3 a.m. Sunday, police were tipped off about a suspicious vehicle in the 0 to 100 block of Marthas Place N.E.

Officers stopped the vehicle and searched it, seizing:

A 20-gauge shotgun.

A collapsible baton.

Brass knuckles.

Bear spray.

They detained two people.

Amarjot Singh Jandiala, 19, has been charged with:

One count of careless transport of a firearm.

One count of unauthorized possession of a firearm.

One count of possession of a firearm without a licence.

One count of possession of a firearm in a motor vehicle.

Three counts of possession of a weapon dangerous to the public.

A 15-year-old male, who can't be named under the provisions of the Youth Criminal Justice Act, faces the same charges.

Jandiala has also been charged with one count of possession of a firearm contrary to a court order.

"This case is extremely concerning given the age of the offenders involved," Staff Sgt. Greg Cooper of the CPS guns and gangs unit said in a release issued Monday.

"Criminal use and possession of firearms can have a huge impact on the safety of our citizens and we take these matters very seriously."

Police ask that anyone with information about firearms offences call the force's non-emergency number at 403-266-1234 or 911 if a crime is in progress. Tips can also be submitted anonymously to Crime Stoppers at 1-800-222-8477 or via its website at www.calgarycrimestoppers.org.
