It happened on Tuesday just after 6 p.m. Yasmeen Haleem of Orland Park was working on a video shoot.
Haleem says two guys ran up behind her, knocked her down and stole her Canon video camera, which is worth over $2,500.
"I was pushed from behind and two guys took off with my camera and equipment. Everything on there I lost from that day as well as invaluable footage from a recent trip in Ohio covering the 2016 Transplant Games," she said.
The suspects were seen in an image from the photoshoot just before the theft.
Anyone with information is asked to call Area Central Detectives at (312) 747-8380.
