Boy, 17, charged with ‘prolonged’ sexual assault of stranger on Blue Line train

CHICAGO — A 17-year-old boy violently attacked and raped a woman he did not know while riding a Blue Line train on the Northwest Side, prosecutors say. Authorities charge Tyshawn Robinson as an adult with criminal sexual assault causing bodily harm.

CTA surveillance video showed Robinson, the 38-year-old victim, and other passengers were riding the same train when Robinson tried to touch the woman near the Addison station around midnight on April 29, officials said.

The woman moved away, but Robinson kept following her. He eventually grabbed her by the body and pulled her onto his lap, prosecutors said in a detention petition. She tried to break free, but Robinson continually put her in a chokehold with her arm and forearm, preventing her escape, according to the allegations.

Robinson forced the woman over a seat in the car and sexually assaulted her at least twice as she fought back, prosecutors said.

Robinson ended the assault and fled when the train’s operator entered the car, according to court filings. A short time later, Chicago police found him nearby.

Judge William Fahy granted the state’s detention petition, saying the “prolonged” attack on a stranger occurred in front of other people, leading him to conclude that electronic monitoring would not be an appropriate option for Robinson.
