The Berks County sheriff's office said it needs help finding Korby Beck.
Beck is wanted for failing to comply with his probation in connection with a charge of accidents involving death or injury.
Beck was also arrested last June after allegedly stealing two large brass railings from the North 6th Street entrance of the Berks County Courthouse in downtown Reading.
Beck, 46, is described by authorities as a white man who stands 5 feet, 6 inches tall and weighs 180 pounds. He has hazel eyes and brown hair.
If you know of his whereabouts, call the sheriff's office at 610-478-6390.
