Calgary Police are left wondering what happened when they were called to the scene of a business on Monday morning where someone smashed a truck through the front door.

They were called to the scene at just after 5 a.m. at 4108 Macleod Trail S.E.

Police say that a truck backed into a pawn shop.

They believe that once that happened, suspects jumped out of the truck and entered the store.

"There is some surveillance video from inside the shop which shows the vehicle backing into the store," says Staff Sergeant Ian Vegso with the Calgary Police Service. "Four people entered the store and within a minute, they left with nothing and jumped into the second vehicle and left the scene."

The truck was left behind, still running. Police say they aren't sure whether or not it was stolen. "It didn't come up on our system as stolen yet."

Vegso says that police have assurances from the shop owner that all the firearms in the store were secured and everything else is accounted for.

They are speaking with the shop owner and reviewing security camera video to gather more information.

Earlier Monday morning, police also reported to the scene of a downtown luxury business.

Police say that at around 4:30 a.m., a Blue Ford Mustang crashed into the front window of the Holt Renfrew store on 8 Ave. S.W.

They aren’t sure was exactly was taken, other than one Louis Vitton bag.

Investigators are also searching an area in Kensington on Monday morning after someone smashed the window of a Telus store.

That incident occurred at about 5:30 a.m. on 4623 Bow Trail S.W.

The suspect reportedly smashed their way in with an object and made off with an unknown amount of merchandise.

Police are continuing to investigate these incidents and similar ones that occurred last week.

On Friday, a truck smashed into the front entrance of Gold Craft Jewelry on Sirocco Drive S.W.

A number of suspects managed to get away with an unknown amount of jewelry before fleeing the scene.

Police are still looking for a dark coloured pick up truck that would have sustained severe damage to the back end in the incident.

And, on September 11, police were called to a Reddi-Mart on 4 St. N.E.

By the time they got there, the vehicle was gone.

All that was left was a gaping hole in the side of the building.

They are still reviewing surveillance video.

At this time, police don't believe that there is any connection between any of the incidents.
