Pima County Sheriff's Department detectives are asking the public for help in identifying a man armed with a knife who stole CDs and videos at a northside Walmart.

On Saturday shortly before 5 p.m., deputies were dispatched to Walmart, 7635 N. La Cholla Blvd., to a report of an aggravated assault, said Deputy Courtney Rodriguez, a sheriff's department spokeswoman.

Deputies talked to security personnel at the store who said they observed a man take CDs and videos off a shelf and put them into a backpack, Rodriguez said.

When the man left the store, he was confronted by a Walmart security worker, she said. The man put the backpack on the ground and walked away.

The security worker confronted the man again, and the man pulled a knife out of his pocket and held it down at his side, Rodriguez said.

The man said "bye" to the Walmart employee, and got on his bicycle and rode south toward West Ina Road, said Rodriguez.

The man, who was captured on surveillance cameras, was described as white, mid to late 40s and about 6 feet tall. He had a goatee and was wearing a black hat and a flannel shirt.

Anyone with information is asked to call 88-CRIME or 911.
