Bystanders pointed Anderson Police in the direction of an assault suspect at McDonald's Thursday. Officers were called to the McMurray Drive fast food restaurant at 2:30PM by witnesses who reported seeing a man threaten a woman with a knife and assault her. Officers spoke to the woman, who was in the corner of the parking lot, and she denied being assaulted. She said her companion was 21-year-old Martin Thietje. He's on parole and had an active felony warrant. Several people told officers that Thietje was hiding in the men's room. That's where he was found and arrested on his warrant.
