Old video store in Waukesha damaged

WAUKESHA, Wis. (CBS 58) -- Some serious damage was done to a building that once housed a family video store in Waukesha. 

It happened around noon on Friday, June 25, near Barney and Broadway Streets. 

The Waukesha Fire Department says they're still not sure what happened. The building is flanked by a Marco's Pizza and a Dollar General. Fire officials say both of those businesses are closed for the time being. 

"They've had an engineer on sight. The engineer is looking at, doing an analysis, and it going to write a report that will let us determine when these businesses can get reopened," said Fire Marshall Brian Charlesworth, Waukesha Fire Department. 

No injuries have been reported. 

The Waukesha Community Development Department is investigating.
