Man accused of dragging woman on to subway tracks

Philadelphia police arrested the suspect caught on surveillance video attacking and dragging a woman across a train station platform before throwing her on to the tracks.

The Southeastern Pennsylvania Transportation Authority (SEPTA) arrested William Clark around 2:30 p.m. on Thursday, 48 hours after he allegedly attacked the 23-year-old woman on a subway platform in the Chinatown section of Philadelphia. Police plan to charge Clark, 36, with aggravated assault, leaving Alexis Wilson with minor injuries.

"Thank God she wasn't knocked unconscious in that track area," SEPTA Police Chief Thomas Nestell told in a news conference on Thursday. Police said Clark walked up to Wilson, who was sitting and waiting for a train Tuesday about 3:20 p.m. Police said the suspect asked her for a lighter, which she gave to him.
