Shortly after 4:30 a.m., a customer found a wounded clerk lying inside a Turkey Hill convenience store in Lower Pottsgrove Township and called police.

The victim, shot in the leg, was transported by helicopter to Reading Hospital and Medical Center in West Reading, where he was in serious but not life-threatening condition, according to a 911 supervisor.

Police are looking for two young black men suspected of trying to rob the store at 3051 East High St. in the community of Sanatoga when the older one shot the clerk with a revolver, the supervisor said.

The gunman is described as in his early 20s, about 6 feet tall, with facial hair. He wore a hooded brown coat, white T-shirt, blue jeans and white sneakers.

The other suspect is in his late teens or early 20s, about 5-foot-10, with short hair and a thin build. He wore a white T-shirt, tan or gray cargo pants and black sneakers, and was carrying a green backpack.

They were last seen running east on East High Street.

No details were available on what, if anything, was stolen, the supervisor said.
