Two men who stole puppies from a Northglenn pet store clipped a witness who tried to stop their getaway car, police said.

The robbery happened about 3:25 p.m. Thursday at Puppies ‘n’ Stuff, 1400 West 104th Ave., according to a Northglenn Police Department media release.

Police said two men entered the store, picked up three puppies and ran out. A witness saw the incident and followed the pair behind the business to West 103rd Place where the men jumped into a black Jeep Grand Cherokee driven by a woman.

As the witness tried to stop the Jeep, the driver accelerated, clipping the witness and knocking him to the ground.

The witness, who was treated at the scene for minor injuries, was not able to pass along details on the license plate to police.

The thieves stole a male German shepherd and two while Maltese puppies.

Anyone with information on the incident, or who recognizes the two men in the surveillance photos, is asked to call police at 303 450-8893.
