Officials say a man has been charged with sexually assaulting a "helpless" woman on a train traveling between Philadelphia and southern New Jersey.
The Camden County Prosecutor's office says 45-year-old Charles Arcano, of Voorhees, is accused of assaulting a 22-year-old woman on the PATCO Speedline train in the pre-dawn hours of Jan. 27.
The assault was captured on video. Arcano allegedly repeatedly groped, licked and fondled the intoxicated woman. At one point she tried walking away from him but he allegedly pulled her into a seat and held her on his lap.
A criminal complaint alleges Arcano "knew or should have known the victim to be physically helpless or incapacitated."
Investigators previously had released surveillance video from a station to help identify a suspect.
Arcano was arrested Tuesday in south Philadelphia and will be extradited to Camden.
He is charged with aggravated assault, sexual assault, aggravated sexual contact and criminal restraint.
A message seeking comment with the public defender's office, which is representing him in Philadelphia, wasn't returned.
