PHILADELPHIA (AP) — A man charged with raping a woman on a commuter train just outside of Philadelphia harassed her for more than 40 minutes while multiple people held up their phones to seemingly record the assault without intervening, authorities said.

More than two dozen train stops passed as the man harassed, groped and eventually raped the woman, the police chief for the Southeastern Pennsylvania Transportation Authority said at a news conference Monday.

Police do not believe a single witness on the train dialed 911. They are investigating whether some bystanders filmed the assault.

Both the man and woman got on the train at the same stop Wednesday night in North Philadelphia. Officers pulled the man off of the woman at the last stop. They responded within about three minutes of a 911 call from a transportation authority employee, authorities said.

“What we want is everyone to be angry and disgusted and to be resolute about making the system safer,” SEPTA Police Chief Thomas J. Nestel III said at the news conference.

Arrest records show Fiston Ngoy, 35, was charged with rape and related offenses.

The affidavit of arrest for Ngoy detailed times of the assault, including that during those 40 minutes the woman appears to repeatedly push Ngoy away.
