EAST PEORIA — A bomb scare at Caterpillar Inc. Building KK ended peacefully Tuesday, police said.

After a bomb threat, police from East Peoria and Peoria checked the building early in the afternoon. About 2 p.m., Peoria police spokeswoman Amy Dotson said no danger was found after a sweep by the department's Explosive Ordnance Disposal unit. 

"All clear," she said.

East Peoria police Chief Dick Ganschow said police responded "in reference to a letter that was found in the building, making a reference to a bomb threat."

Dotson said she knew of no arrests relating to the threat.

As of 1 p.m., Caterpillar had not evacuated the building. But later that hour, employees were dismissed, said Caterpillar spokeswoman Corrie Heck Scott.

"Caterpillar takes seriously the safety of all of its workforce," she said in a statement issued at 2:15 p.m. "After following our safety protocols and in consultation with local authorities, it was determined that an evacuation of the facility was not necessary. We have now received an all-clear from the authorities. However, we have decided to release first-shift employees early. Second shift will continue as scheduled."
