UPDATED 8:10 p.m. Tuesday--Clinton Township police continue to search for the lone gunman who opened fire on a gas station clerk Tuesday morning during an attempted robbery.

Police say that at about 2 a.m. Tuesday, the gunman entered the Mobil gas station near Harper Avenue and Denton Street and shot the 42-year-old clerk four times, including once in the eye.

When the gunman was unable to open the computer-operated cash register, he fled the scene.

Det. Capt. Richard Maierle said the suspect was wearing at least three layers of clothing and a scarf to conceal his face at the time of the robbery. He is described as a black male, between 5’7” and 5’10”. Detectives are currently reviewing surveillance video.

The clerk has since undergone surgery for his bullet wounds, but his current condition is unknown, Maierle said.

Anyone with information about the shooting is asked to call the Clinton Township Police detective bureau at 586-493-7840.
