He became unruly, and punched an officer when AMED personnel tried to get him into an ambulance to go to the hospital. Johnson allegedly told police he took some kind of hallucinogen. He is charged with aggravated assault, resisting arrest, criminal mischief and simple assault. He is locked up in the Blair County jail.
