AYER - The Ayer Police are seeking the community's assistance in the hunt for a robbery suspect who struck a Littleton Road gas station on Sunday night.

At approximately 7:47 p.m. Sunday night, a masked man entered Partridge Automotive (also known as Smart Fuels, formerly A.L. Prime Gas Station) at 42 Littleton Road (Route 2A). The man demanded cash while brandishing a 6-8 inch knife. The clerk was not injured in the incident, and the man was believed to have fled the store on foot. There was no known direction of travel for the suspect.

Initial reports were that the man was described as being in his 20s, about 5 feet, 8 inches tall, and weighing approximately 250 pounds.

From the surveillance images taken inside the store, the man is apparently wearing light colored pants, a plaid over-shirt, a head covering and a black mask over his face.

Rather than estimate what the man looked like or was wearing, the Ayer Police request that people review this photo of the man. The image was gleaned from the store's security camera.

Ayer Police called in assistance from the Harvard, Shirley, Groton, Littleton and State Police, which responded with a K-9 unit for a sweep of the area Sunday night. The robbery occurred shortly before the gas station was due to close at 8 p.m., confirmed Ayer Police Lt. Brian Gill. Police are not disclosing the amount of money taken in the robbery, stating the sum itself is important to the investigation.

If you can identify the person in this photograph, or were in the area and observed anything, please contact Ayer Police Detective Andrew Kularski or Officer George Fichter at (978) 772-8200.

The same gas station was robbed on the night of Wednesday, May 3. Gill confirmed that there was a different clerk on duty during the May incident than during Sunday's robbery.
