Benjamin Murphy, 29, is wanted for a robbery in which a gang ram-raided a jewellers in Sheffield and escaped with £1.6m worth of diamond rings and watches.
Murphy, from Manchester, has been on the run since jumping bail 18 months ago.
Although South Yorkshire Police had confiscated his passport he was able to apply and get a replacement, claiming he had lost the original.
Two of Murphy's cousins are already serving long jail sentences for their part in the robbery, from which most of the jewellery is still missing.
Shop owner Gary Singleton said: "He's done a runner and got away with a lot and is living the high life. If he's done the crime he should be doing the time."
Are criminals hiding among tourists?
Murphy is described as stocky with green eyes, shaved, dark brown hair and Chinese dragon tattoos on his chest and right arm.
