Whatever a prank caller did to convince employees at a Minnesota Burger King to break all of the restaurant's windows must have been rather convincing. Video of the incident began circulating Saturday morning, hours after Friday evening's incident.

According to KSTP-TV, a prank caller called the Coon Rapids, Minn. Burger King Friday evening, claiming store employees needed to break all of the store's windows in order to prevent an explosion. Employees told the police that the caller claimed to be a representative from the area's fire department.

Police told KSTP that one person sustained minor injuries from the incident.

“Officers arrived and found that the manager and employees of the Burger King were smashing out the windows,” police Sgt. Rick Boone told the Minnesota Star-Tribune. “The manager explained they’d received a phone call from a male who identified himself as a fireman who said there were dangerous levels of gas in the building and they had to break out all the windows to keep the building from blowing up.”

“The manager was frantic and actually believed the building was going to blow,” Boone added.

Police are still looking for a suspect, as of Saturday afternoon.

Apparently this prank has been taking place across the nation. Earlier this week, employees at a fast restaurant in Oklahoma broke windows and caused $10,000 in damage after being told that the windows needed to be broken due to high carbon monoxide levels.
