Police swarmed two Delaware County, Pennsylvania shopping centers on the ground and by air Friday night after a bomb threat was phoned in to authorities.
A man called the Wal-Mart along the 600 block of Conchester Highway in Boothwyn just before 10 p.m. and said there was a bomb left there, police tell NBC10. Right after, he called a Rite-Aid about a mile away to say a bomb was left on the roof, authorities said. Both stores then called police.
Officers responded to the area and evacuated every store and several fast food restaurants. Roads in the area were also shut down, police said.
A Wal-Mart shopper told NBC10 that while evacuating, she was told police were investigating a suspicious package under a car in the parking lot.
Police K-9 units were called in to sweep the area. Philadelphia Police's tactical air unit also came to help by checking the building roofs for any devices.
Police did not find any devices.
The stores reopened at normal hours Saturday.
