A gang snared after police discovered a Breaking Bad-style drugs lab have been jailed for a total of almost 20 years.

Detectives had swooped at an industrial yard in Glasgow's Dennistoun last December.

They found a Ford Transit which had been kitted out inside to “adulterate and package drugs”.

Police went on to seize £1.7m of cannabis and cocaine during the large scale probe.

Four men held following the raids were sentenced at the High Court in Glasgow.

Convicted dealer Robert Wright – once stripped of his expensive art collection – was jailed for eight years.

The 55 year-old, of Milton, Glasgow, pleaded guilty to being concerned in the supply of cannabis.

Terrence Connelly, 31, of the city Robroyston, was locked up for six years after he admitted cocaine dealing.

Brian McCulley, 39, of Baillieston, and Peter Ewing, 53, of Bridgeton, both Glasgow, each pleaded guilty to the same charge as Wright.

They were sentenced to three years and 32 months respectively.

The four were snared as part of the Operation Croupier probe.

Wright was clocked driving a Mercedes into the yard before McCulley and Ewing turned up in a Ford Mondeo.

The trio stood chatting before McCulley and Ewing left.

The pair were eventually held close to Lochwinnoch train station in Renfrewshire.

A total of 38kg of cannabis and cannabis resin was discovered in the Ford.

Wright - described as the "custodian" of the yard - was held later that day after he returned there.

Connelly meantime was clocked driving another Mercedes into the site.

Detective Inspector Mark Carruthers from Police Scotland’s, Specialist Crime Division said: “This operation was designed to disrupt and dismantle those involved in Serious and Organised Crime, who are supplying drugs throughout Scotland.

"The recovery of this amount of drugs has had a massive impact in our communities and the sentences send out a strong message to those involved in drug supply and Serious and Organised Crime, that we will not tolerate their behaviour”.
