Quote:ADDISON, Ill. (Associated Press) -
A gun was accidentally discharged by a criminal justice instructor at Technology Center of DuPage during a class, striking a file cabinet and wall.

School director Jim Thorne said the instructor, a retired FBI agent he didn't identify, wasn't authorized to have the gun on the school's property in Addison.

The Daily Herald in Arlington Heights reports three students were watching the instructor's demonstration Friday when the incident occurred. No one was injured.

School officials say the instructor was escorted from the building after the incident and placed on administrative leave. Thorne said the instructor's future status won't be determined until after an investigation is complete.

Addison Police Department Director Tim Hayden says the instructor has been questioned, but a decision on whether he'll be charged hasn't been made.
