LAKEWOOD, Colo. — A stolen concrete truck was used by two suspects in a smash-and-grab burglary at a gun shop early Tuesday morning, the Lakewood Police Department said.

The burglary happened about 4:20 a.m. at Green Mountain Guns at 3355 S. Yarrow St., not far from West Hampden Avenue and South Wadsworth Boulevard.

Police said the concrete truck was stolen out of Arvada by two suspects wearing jackets, hoodies, gloves and masks.

They then drove to Lakewood and tied a cable to the front of the truck, then attached the other end to the front doors, backing up and ripping them off.

“We’re concerned because now we have a few guns on the street in the hands of criminals,” police spokesman Mark Reeves said.

Police did not release any suspect descriptions but believe a getaway vehicle was used. Police have not heard from any witnesses and did not have a description of the vehicle.

In June 2017, Green Mountain Guns was hit in an attempted smash-and-grab burglary. Suspects tried to ram a stolen Jeep into the store but were stopped by metal posts in front.

After that attempt, the store owners put two concrete barriers in front to deter burglary attempts.

The owner of the gun store said he’s already looking into how he could add even more security.

“We have some ideas because we’re not the only ones this has happened to,” Mike Cook said. “In our case, it did take a cement truck to breach the perimeter.”

Attempts were made over the summer by suspects to get into the store but they failed. This is the first successful burglary at the store.

Police are asking if anyone who might have seen the truck driving around in the middle of the night to call them.
