He was one of a group of young men captured on camera walking north along George St, early on Sunday, August 4.
Investigation support unit supervisor Richard Bourne said one of them "king-hit'' the door of the 2 Degrees shop near Albion Pl, about 12.45am, causing about $700 worth of damage.
Police wanted to hear from anyone who could help identify the group.
