SOUTHFIELD, Mich. -

Southfield police have released pictures of the truck thieves used to bust into a gun store this week.

Police said the 2011 Ford van, which was being used by Henry Ford Health System, was stolen from the 21000 block of Melrose and then rammed through a wall at Action Impact on 8 Mile road.

Store owner Bill Cucyk found the damage Wednesday morning.

"They smashed the wall in two locations, behind the range and behind my classroom," said Cucyk.

At least 20 guns were stolen.

"We have a concern that there are a couple of guns that may be out on the street and I think that everybody in the Detroit metropolitan area needs to be aware of that," said Cucyk.

The men wore hooded sweatshirts and masks.

"If they any information, if anybody is trying to sell some guns, please call police," said Cucyk.

Federal investigators are working with Southfield Police on investigating the crime. They are going over several minutes of surveillance video to hopefully identify the two suspects that pulled off the crime.

Anyone with information on the robbery or truck is asked to call 248-796-5500.
