Shortly before 1:00 Saturday afternoon, Knoxville Police Department received a call of a man knocking on car windows stopped at the intersection of Main and Second Streets, on the Knoxville square. When officers arrived, they located 28-year-old Knoxville resident Shawn Douglas Weihs, and in talking with him, found probable cause to arrest him. He resisted, and a second officer was called. He continued to fight, and the second officer tased him. According to Chief Dan Losada, the officers realized at this point Weihs had a medical condition and chose to use muscling techniques to subdue him, instead of using the taser a second time. He was arrested and taken to Marion County Jail, charged with interference with official acts, possession of a controlled substance and no drug tax stamp. Weihs was examined by Knoxville Fire and Rescue staff, and was not hurt in the altercation.
