Gangland torturer Colin Coats has formed a close bond with drug baron Mark Richardson behind bars.
Killer Coats, 51, told prison chiefs that a knife found in cocaine dealer Richardson’s cell belonged to him. He confessed to owning the weapon after prison guards carried out a search in HMP Glenochil, near Stirling.
Sources say the pair have developed a relationship in the top-security prison. However, insiders cast doubt on Coats’ claim the weapon – found last month – belonged to him.
