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.
