Longer jail terms for drug traffickers Gavin McFadyen and Adam Lyttel

Two drug traffickers have had their jail terms increased after the Crown challenged the sentences handed out by High Court judge Lord Brailsford.

Appeal judges doubled a four-year term imposed on Gavin McFadyen. He organised and directed cannabis couriers and took part in a cocaine handover.

In a separate case, Adam Lyttel saw a 40-month sentence almost doubled to six years imprisonment.

Lyttel was caught with cocaine with a potential street value of up to £1.6m.

McFadyen, 40, from Cumbernauld, North Lanarkshire, and Lyttel, of East Kilbride, South Lanarkshire, were both jailed by Lord Brailsford last year at the High Court in Glasgow.

McFadyen, who was out on licence from a previous six-and-a-half year prison sentence imposed in 2003 for drugs and firearm offences, admitted being concerned in the supply of cannabis in 2008 and cocaine months later in 2009.

He was the target of a police surveillance operation that resulted in more than 250 bars of cannabis resin, with a potential street value of £266,427, being recovered.

He was later seen to pass on a package at a car park in Glasgow to a man who was followed to Dundee, where he was stopped and found with cocaine worth up to £86,000.

First offender Lyttel was stopped by police in 2010 on the M74 in South Lanarkshire after intelligence was received.

Almost three kilos of high purity cocaine were found in a rucksack in the boot of the car he was driving.

He had travelled to motorway services near Preston, in England, to collect the drugs.

Lyttel also stored and distributed drugs and collected debts working for others.

The Crown appealed against the sentences, claiming that they were unduly lenient.

The Lord Justice Clerk, Lord Gill, sitting with Lord Menzies and Lord Wheatley, said they would allow the appeals in both cases.

Lord Brailsford originally gave McFadyen sentences of two and four years for the cannabis and cocaine offences, but made them concurrent.

The appeal judges increased the lower sentence to four years and made it consecutive to the other prison term.

In Lyttel's case, the sentencing judge had started with a sentence of five years but reduced it to 40 months after he admitted the charges.

The appeal judges said they would have started with an eight-year sentence and would cut it to six years to take account of the plea.
