CTA Bus Driver Tips Off Police, Leading To Arrests In Subway Robbery

When a vigilant CTA bus driver overheard two young men discussing what sounded like a recently-completed robbery, she decided to do something about it.

The driver of a northbound Harlem CTA bus called the police after Tevon Woods and Alvon Hoskins, both 20, were dropped off at a restaurant in Niles, leading to their arrest Tuesday, the Chicago Sun-Times reports.

Moments before Woods and Hoskins boarded the bus, a man who was listening to his iPhone while exiting a Blue Line train was grabbed from behind by his backpack and pulled down the Harlem station's escalators with such force that the straps broke, causing the backpack to fly onto the tracks, according to the Chicago Tribune. Two robbers then grabbed his phone and fled the scene.

Police apprehended the pair at a fast food restaurant, where Woods was waiting in line for food and Hoskins was found hiding in the restroom, the Sun-Times reports. The victim's iPhone was found in a garbage can in the bathroom.

Woods and Hoskins were each charged with one count of robbery and are each currently being held on $200,000 bail. They face up to seven years in prison if convicted, the Tribune reports.
