DELAWARE COUNTY, Pa. (CBS) — A preliminary hearing for Fiston Ngoy, the suspect charged with raping a woman on the El train last month, will be continued at a later date. Eyewitness News has learned the 35-year-old’s hearing is being rescheduled for Nov. 29 due to some staff changes on the District Attorney’s side of the case.

Authorities said Ngoy raped a woman aboard the train on Oct. 13 around 11 p.m. He has been in a Delaware County prison on a $180,000 bond ever since his arrest.

The assault originally made national news after reports of riders watching and even videotaping the incident, which was reported by authorities. The Delaware County District Attorney later said that was not true; he said security video caught one passenger recording part of the interaction, but it was unclear if the passenger fully understood what was going on.

Upper Darby Police Superintendent Tim Bernhardt says it was a SEPTA employee who alerted police.

Police say the suspect and the victim did not know each other.
