Police search State Farm HQ in Ill. for intruder

Authorities are checking out reports of an intruder with a gun at the headquarters of State Farm insurance in Illinois.

Company spokesman Frasier Engerman says employees aren't being allowed to leave Thursday afternoon while police investigate. He says no one is injured.

Bloomington Police Lt. Joe Butcher says officers have locked down the building. He says police got a call from someone who saw a man with a gun headed toward it.

Engerman says 4,000 people work at State Farm's headquarters. Some may have gone home early because of the holiday weekend.
