DES PLAINES, Ill. -- A man had to be removed from a Megabus after he fired a gun onboard.
The bus was going from Chicago to Madison, when a gun was fired inside the bathroom.
Passengers say the man came out and started harassing the driver, grabbed her and made a play for the wheel.
Witnesses say that gun clip was fully loaded.
One of the passengers jumped in to help the driver, and confronted the armed man.
"He was saying something, but it didn't make sense," said Kenneth Smith. "I noticed that (the bus driver) was pushing him off of her. Because he had her by the arm, like he was pulling her, like he was trying to drive."
Smith says he confronted the man and told him to go back upstairs. He says the man did that, but then he came back with a gun.
"He was grabbing at his hip, and I told him he was getting too close. As he kept coming, that's when I rushed him. I choked him, he fell to the floor, and the clip fell out of the gun."
"That gentlemen right there, he saved us," said another passenger.
The bus stopped at the Des Plaines Oasis, where police took the man into custody.
He is being held at the Des Plaines Police Department, but no charges have been filed.
Megabus put the other passengers on a new bus to finish their trip.
