The bomb squad was called Thursday morning to the state Capitol after a sleeping bag and shoulder bag were left near the south steps of the state government building.
Oklahoma Highway Patrol diverted visitors from the southeast entrance briefly Thursday morning while the suspicious items were investigated.
Highway Patrol Capt. Paul Timmons said they took extra precautions because May 1 marks the 1-year anniversary of Osama bin Laden's killing.
“Just being on the safe side, didn't want to take any chances,” Timmons said.
The items belonged to a homeless man who was found inside the Capitol, Timmons said. He was detained and questioned, and the bag was determined not to pose a threat.
