Two men are being sought in connection with a robbery at Wal-Mart Thursday. Bessemer police say a man demanded money from the bank located inside the store, and claimed he had a bomb.  A short time earlier, a bomb threat was made against the Wal-Mart in Hueytown.  Police said they were looking to see if the two events are linked. The FBI said one suspect is described as a white man, clean shaven, wearing a dark colored hoodie, green shirt, and blue jeans. The second suspect was described as a black man wearing dark-colored clothing, and a dark ballcap. They may be traveling in a silver or tan Toyota Camry.   Anyone with information should call Hueytown or Bessmer police, or the FBI.
