A £2,000 reward is being offered for information on one of Scotland's most wanted men.

Martin Hamilton was released from prison in September last year but is now wanted for breaching the terms of his licence.

The 53-year-old from Anderston, who was once dubbed the ‘Blackhill Butcher’, is described by officers as “dangerous”.

Police have urged members of the public not to approach him but to contact officers if he is seen.

The 53-year-old is described as white with short, cropped, fair hair.

Detectives have been hunting him for six months but have found no trace of him and believe he is being helped by others. A reward was offered back in July in a bid to try and track him down.

Now Crimestoppers have reissued their offer of a £2,000 reward for information leading to the arrest of Hamilton and an appeal has featured on the BBC's Crimewatch programme.

He is thought to regularly visit bookmakers and shop workers and customers are being asked to look out for him.

Detective Inspector Brian Gallagher said: "A significant amount of enquiries have been undertaken by officers working on the inquiry, however despite efforts, these have so far drawn a blank.

"It is clear that Hamilton is receiving assistance from associates in order to evade capture by police. This includes financial assistance - as there has been no trace of him withdrawing money from his bank account.

"Intelligence we have suggests that Hamilton may be frequenting licensed bookmakers, so I'd ask anyone who uses these establishments across the Scotland area to keep an eye out.

"Similarly I'd like those who work in these places to study Hamilton's image - have you seen him in your bookmakers? If so, contact police.

"Crimestoppers have put up a significant reward for information leading to the arrest of Hamilton. I would ask anyone who may know where he is to consider this reward carefully and I would stress to anyone who has information in relation to Martin Hamilton to pick up the phone and contact us.

The information can be provided anonymously through Crimestoppers and the reward will be provided for information leading to the arrest of Martin Hamilton.

"I would urge anyone with information to contact police immediately on 101.

"Information can be passed to Crimestoppers by calling 0800 555 111."

Before he was jailed for life, Hamilton walked free from twelve High Court indictments for crimes including possession of firearms, a shooting, serious assault and robbery.

Justice caught up with him at the High Court in Inverness where he was convicted of drug dealing offences and ordering the kidnap and torture of victims from the Edinburgh drug scene.

In one incident Hamilton attempted to gouge a man’s eye out with a spoon. He also tried to cut a
