Police are investigating the late-night robbery of a west Shreveport convenience store. It happened just after 10 last night, at the Circle K in the 6000 block of West 70th Street. Police have been told that a man wearing a white t-shirt with writing on the front, dark pants and a dark mask walked in with a large wrench and went behind the counter. He threatened employees and demanded cigarettes, grabbed a number of cartons and left on foot. No one was hurt.

Investigators believe this is the same man who robbed a Circle K in the 300 block of Kings Highway back on May 13th...and a Valero in the 1300 block of Kings on May 18th.  Take a look at the surveillance photos posted here, and if you recognize the man in them, call Shreveport detectives or Crime Stoppers -- 673-7373.
