FULTON RIVER DISTRICT — New video released by the Chicago Police Department shows a man in a bike shop they believe to be the gunman on a bike who shot a 29-year-old woman Downtown Wednesday.

The man in the video, wearing a black baseball cap, black clothes, a black backpack and white sneakers, brought his mountain bike into the shop less than an hour before the shooting just before noon Wednesday, according to police.

In the video, the man’s face is seen as he removes the baseball cap and wipes his head with a paper towel.

Police released the surveillance footage late Thursday and uploaded the video on Facebook early Friday morning.
