PORT CHARLOTTE, Fla.- Charlotte County Sheriff's detectives are asking for the public to help identify an armed robbery subject who used a knife to demand money from the owner of the Asian Cai Lay Market in Port Charlotte on Thursday.

CCSO responded to a hold-up alarm on at 7:11 p.m. at 1380 El Jobean Road. The 43-year-old owner told deputies a man came into his store with a knife and demanded money from the cash register. The manager refused to open it and the robber then pointed a knife at a 19-year-old customer, demanded his money, and then fled around the back of the business. K9 was called and attempted to track with negative results.

A BOLO was issued for the subject, who is about 6 feet tall, weighing about 180 to 200 pounds, wearing a large farmer’s style hat, had a blue cloth over his face, and was wearing a light-colored, long-sleeve shirt or light weight jacket.

If anyone has information about the possible identification of the subject shown in the store surveillance photos, please call CCSO Detective Paul Underwood at 941-639-2101, or Crime Stoppers at 800-780-TIPS (8477).
