NASHUA - Nashua police released a photograph of a man they believe robbed the Shell gas station last month.

The gas station/convenience store at 301 Main St. was robbed at 8:10 p.m. on Sept. 29 by a man who stole some items and threatened to stab an employee although no weapon was shown, according to a news release.

The man ran out of the store heading west on Lake Street and was gone before police arrived.

He is described as a "very tan" white man in his late 20s to early 30s, about 5-foot-8 to 5-foot-9 and weighing 160 pounds. His face was "sunken" looking - very thin, long and with high cheek bones.

The thief was clean shaven and employees believe he has green eyes. He wore a gray knit hat, red fleece-style jacket with a small logo on the left upper arm, dark cargo-style sweatpants and brown shoes.

Anyone with information about the man or the theft is asked to call police at 603-594-3500. Information also may be provided anonymously by calling Nashua Crime Line at 603-589-1665.
