The Knox County Sheriff's Office is asking for the public's help to find a man who robbed a west Knoxville convenience store with a knife.

Investigators say the man came into the Bread Box at 1606 Lovell Road Thursday morning around 3:30. He went behind the counter and told the clerk to give him all the money in the register.

He got away with an undetermined amount of cash and was last seen walking north on Lovell Road.

The suspect is described as a white male, 20-30 years old, 5'8-5'11, and 180-200 pounds. He was unshaven and his facial hair was dark brown. He was wearing a dark colored toboggan with a white stripe and a green, gray and blue plaid flannel type hooded jacket, blue jeans, and black athletic shoes.

Anyone with information is asked to call the KCSO at 215-2243.
