Police have released suspect information relating to a violent robbery that occurred at a downtown gas station in the summer.

Ryan Foster, 30, is described as a five-foot-eight to five-foot-10 man, with a muscular build and multiple tattoos on his body, including stars on his left chest and the words “Foster Baby” on his right hand.

Police consider him dangerous and ask that anyone who sees him not approach and instead call 911.

At around 4 a.m. on June 13, police say an armed man disguised with a baseball hat and hoodie pulled tight around his face entered a gas station at Front and Sherbourne streets, pointed a knife at the clerk and demanded he open the cash register and lay on the floor.

The man then took money from the till as the victim remained compliant on the floor, police say.

After taking the cash, but before hopping over the counter and leaving, the suspect repeatedly stomped on the victim’s head, rendering him unconscious, police say.

The victim was later transported to hospital, suffering from a fractured eye socket and skull with cuts and bruises on his face.
