Gun goes off on CTA bus, bullet fragment grazes female passenger

Chicago police are hoping surveillance video will help them track down a person who left a gun on a CTA bus before it went off and wounded a woman on board.

It happened on the number 47 bus around 6:30 Wednesday morning near 47th and Kildare on the Southwest Side.

CTA officials say the gun was sitting on a seat and fell onto the floor of the bus.

They say a male passenger who was traveling with the victim picked it up, thinking it was a toy or a lighter.

He accidentally fired the gun, hitting a vent below a row of seats.

A bullet fragment grazed the woman’s left hip.

Guns are not allowed on CTA under the state’s new concealed carry law.
