LORAIN — Lorain police are looking for a man who robbed a Dairy Mart at gunpoint this morning and assaulted the clerk.

Officers were called to the convenience store at West 28th Street and Broadway at 5:30 this morning, according to a police report.

The clerk told police he was in a back room when a man he recognized as a customer of the store for at least the four years he’d worked there entered the store and walked to the beer cooler.

When the clerk came out of the back room to see the man holding a silver revolver, the report said. The man then began yelling and running at him. The robber jumped over the counter and attacked him, striking him in the head with the barrel of the gun and leaving a lump, the clerk said.

The clerk said the man pulled him to the register by his hood and demanded he open the drawer, the report said.

The man emptied the register and fled, making off with $331.

Police described the man as a black male about 6 feet tall with a thin build. He was wearing half a face mask, a dark hooded sweatshirt, dark pants and white gloves.

The clerk said he recognized the man as a customer based on his voice, eyes and nose and identified him by his street name, the report said.

Police searched area but did not find the man.

Police took a VHS tape of the robbery as evidence and searched for fingerprints but could not recover any. The owner of Dairy Mart is processing four other video cameras, according to the report.
