TWO drug dealers associated with murdered Glasgow gangster Euan Johnston have been jailed for playing a key part in his GBP 600,000 heroin trade.

Ex squaddie Brian McMahon - who was sitting with Johnston when a gunman assassinated him - was sentenced to three years and three months.

The 30-year-old's DNA was found on a bag containing heroin worth at £17,600 which police recovered from the boot of a car they stopped in Possil on 5 March 2014.

Gary Bradburn, 39, was sentenced to five years and three months for running a drugs factory in his home in Glasgow's Keppochhill Road.

McMahon and Bradburn admitted heroin dealing but their former co-accused Johnston died before he could be brought to justice.

Johnston was shot repeatedly as he sat in his flash Audi in Kinning Park, Glasgow, last November.

The trio's case was the latest linked to 40-year-old drug baron Roy Dunstance, who is serving 11 years for running a £9m drug and gun empire from Spain.

An earlier hearing was told McMahon was suffering from post traumatic stress disorder after witnessing the brutal murder.

Passing sentence, judge Lord Clark said he accepted that both accused had been operating at the lower end of the drug-dealing scale.
