Police are releasing pictures of the man who robbed the Petro Can Gas Bar on Dawson Road Wednesday morning. Constable Julie Tilbury says the man had his hood pulled up to hide his face. He approached the till and pulled a syringe out of his pocket and demanded money. He's described as being in his early 20's with a medium build. He was wearing a two tone grey winter jacket with a hood, blue jeans and white runners.
