AUGUSTA — A runaway commercial paper-shredding truck with no driver at the wheel slipped into gear while it was parked in downtown Augusta Monday morning, crashing into a cement wall but not hitting any other vehicles or causing injury, police said.

The driver, Craig Knox, 60, of Rome, had parked the Shredding on Site truck on Oak Street, a short uphill street that runs between Water and Commercial streets in the middle of the city’s downtown, according to Lt. Christopher Read of the Augusta Police Department.

Knox got out of the truck to run the shredding machine and the truck apparently slipped into gear, Read said. The truck moved forward across nearby Commercial Street and into a concrete, city-owned retaining wall just off the road.

A section of the wall appeared to be knocked over by the truck. The 2013 Peterbuilt box truck sustained front end damage.

Traffic was briefly blocked to allow for removal of the truck.

No charges have been filed in the incident.
