Two employees at a Circle K convenience store in Globe, Ariz., got a call on Wednesday night, from someone pretending to be Circle K's head of corporate security.

He told them the silent alarm was going off and they had to take care of it.

He told them to spray fire extinguishers all around the store and then throw those fire extinguishers through the windows.

But that wasn't it.

He also instructed them to destroy all the merchandise, the registers, security cameras and computers.

In less than five minutes, they completely trashed the store, smashed all but one window but one and did about $30,000 in damages. And somehow the two employees never caught on that it was a prank, KSAZ-TV Fox 10 News reported.

The store shut down for about 12 hours while the windows were boarded up, but Circle K would not say whether it plans to fire the employees.

Police said the pair will not face criminal charges. However, the guy who made the prank call could face charges, but there police currently have no suspects.
