A courier was caught transporting more than £400,000 of cocaine from Glasgow to Dundee.

Ryan Stewart, 41, of Dundee, had recently been made redundant when he agreed to transport the drug in March in a "one-off journey".

Stewart was arrested after detectives acting on a tip-off searched his car in a Dundee car park, the High Court in Glasgow heard.

Officers discovered a bag containing more than a kilo of the drug, which was found to have a purity of 80% - the normal street purity is 10%.

He admitted being concerned in the supply of cocaine and was sentenced to three years and four months in prison.

Judge Lady Scott said: "I accept you acted as a courier on a one-off journey for payment of £300..

"I accept your participation was at a very low level and you have a history of stable employment. I'm persuaded that this is an isolated incident."

Prosecutor Maryam Labaki said: "Should the 80% cocaine be cut to the average purity of 10%, it would have a maximum value of £405,684.

"During the interview he admitted to being paid £300 to act as a courier."

Stewart was the only person in the car at the time of his detention and was taken to Dundee's police headquarters.
