Police say a state Department of Workforce Development auditor who had just received a poor job review shot at co-workers at an agency office in the northwest Indiana city of Portage.

No one was injured.

Sgt. Keith Hughes says the 60-year-old man became upset during his job review Friday and told his supervisor he needed to go to his car. When the man retrieved a shotgun, a manager locked the front door of the office and ordered the other 15 employees to the rear.

Police say the man fired one shot at the front door and another into the office as his co-workers fled. They say he surrendered at gunpoint to officers while trying to reload.

The shooter's name hasn't been released pending formal charges.
