UPDATE: Man argued with Megabus driver after accidental shooting

(DES PLAINES) A man who accidentally discharged his weapon while using the bathroom inside a Megabus traveling on the Jane Addams Memorial Tollway in Des Plaines Tuesday night was ultimately subdued by a passenger and held until police arrived.

About 11 p.m., the man – who was only said to be an adult – got into an argument with the driver after he discharged his weapon and asked to get off the bus, Illinois State Police said. The driver declined and the man went back to get his belongings from the back of the bus.

After securing his belongings he walked back toward the driver and stumbled, causing his pistol to fall out of his waistband, police said. A passenger saw the gun come out and quickly subdued the man and held him until troopers arrived at a parking lot off I-90, just east of Elmhurst road, police said.

No one was reported injured.

Police said Wednesday morning they were having a difficult time identifying the man as he was not cooperating with investigators and he had “no ID, no nothing on him.”

Further details were not available.
