An overnight fire that damaged a downtown Salina building is under investigation.

First responders were called to a fire just after 1:00 Friday morning at the Salvation Army Thrift Store at 157 S. 5th Street. There was smoke and flames, on the outside of the back of the building. Firefighters were able to quickly get it under control, and kept it from spreading into the building.

Officials from the Salvation Army tell KSAL News that though there is no structure damage to the inside of the building, there is smoke damage. The store was able to open for business Friday.

The fire started on a mattress, which along with other multiple items had been dropped off behind the building sometime after the store closed Thursday night.

While the Salvation Army appreciates donations, they ask that they be made during business hours. Large amounts of items being dropped off after hours is becoming an issue.

There were no injuries in the fire.
