Police have been searching for a man who reportedly threatened to shoot up a southwestern Pennsylvania Wal-Mart during a phone call.
The angry caller customer was upset about the store's return policy.
Officers from South Strabane Township and three neighboring municipalities responded to the store at Trinity Point shopping center about 9 a.m. Tuesday.
That's about 20 miles southwest of Pittsburgh.
Wal-Mart officials aren't commenting, though the store remained open.
Police were patrolling the parking lot and watching the store's entrances while they worked to trace the telephone call in hopes of identifying the man who placed it.
