BOONE, N.C. -- Officials are being tight-lipped on the details about an explosive device found at Wal-Mart. Police only told Eyewitness News it was "disrupted" and "diffused."

Police say no one was injured by an explosive device that was detonated by a bomb squad at a Boone store.

Detective Matt Stevens of the Boone Police Department said the device was found at the front entrance of Wal-Mart by an employee about 5:40 a.m. Sunday. One worker said the package was smaller than a shoe box.

The store was evacuated for about five hours while a bomb squad from Wilkes County was called in to examine it. The store re-opened around 10:30 a.m. Sunday.

Stevens says the device was dangerous, but refused to further describe it. The only thing police said was the device would appear dangerous to the average person.

One shopper said he believed it's just a case of teenagers trying to have fun. He says no arrests have been made.

Authorities ask anyone with information about this incident to contact the Boone Police Department at 828-268-6900 or the Watauga County Crime Stoppers at 828-268-6959.
