AUSTIN, Texas - A Goodwill employee was injured by an old military device, not a package bomb, on Tuesday evening. 

An explosion was reported at the Goodwill location on 9801 Brodie Lane around 7 p.m. 

The device was originally reported as packaged bomb, but it was a military artillery simulator, which is a training device that is supposed to mimic grenades and other explosives used in combat.

One man in his 30s was injured after handling the device, however. He was treated and released from the  St. David’s South Austin Medical Center, according to a hospital spokesperson. 

The Austin Police Department does not believe that this explosion is related to the package bombings from earlier this month in Austin. Authorites also do not believe that this was a copycat event. 

The device was dropped off at the Goodwill in a box, and it went off after Goodwill employees determined that it was not an item that they could use or sell. 

Authorities are reviewing security camera footage from the area to determine who dropped off the box. 

Austin residents are still being asked to be vigilant and report any suspicious packages to 911.
