MEDFORD — A man armed with a knife robbed Lumpy's tavern in Medford Friday night, escaping with an undisclosed amount of cash.

The man entered the tavern at 801 S. Riverside Ave. at about 7:40 p.m. and demanded money from a female clerk, according to the Medford Police Department.

"It looked like a decent-sized blade," Medford police Officer Scott Clauson said.

Surveillance video inside the tavern shows the man pointing the knife at the clerk during the heist. There were two customers inside the tavern when the robbery occurred, Clauson said.

The suspect was described as white, 25 to 30 years old, 5 feet 8 inches to 5 feet 9 inches tall, with a thin build, police said. He was wearing faded blue jeans, a blue zip-up hooded sweatshirt and a cap.

The man ran off and disappeared before police could put a cordon around the neighborhood.

Clauson said witness reports at the scene gave conflicting information on whether the man had a mustache. The surveillance video appears to show he does have a mustache, he said.

Clauson said Friday's robbery is not related to the rash of Purple Parrot holdups dating back to April.

"The circumstances were different than the Purple Parrot robberies we've been seeing," Clauson said. "In those robberies the suspect used a gun and hid his face with a mask."

Although police quickly established a perimeter around the location, they were unable to find the suspect.

Anyone with information regarding the case is asked to contact the police department at 770-4783.
