About two hours later, a man with a similar description committed another robbery at a Clark gas station in Mokena. A surveillance camera at that gas station took pictures of a man, again wearing a tan coat but also a grey sweatshirt with the number three printed on it. He also wore work gloves
Then, at 12:15 Thursday afternoon, a third robbery was committed at a Citizens Bank in Palos Heights. The bank's surveillance camera captured images with a similar-looking man wearing a ski mask.
In all three robberies, the suspect displayed a knife with a green handle.
Anyone with information should call police.
