A 52-year-old Clifton Park man is facing criminal charges after a disturbing incident Tuesday morning near Schenectady High School. Several students tell police they yelled at someone who was driving erratically just after 8:15 am. At that point, police say Ulysses Wynn got out of the car and confronted one of the teens....slapping her in the face. Police say he then grabbed her by the throat and began pushing her towards a moving bus. A second teen was able to get Wynn away from the girl. Neither teen was seriously hurt.
