Eight people jailed for total of 82 years for Wiltshire drugs offences
It's after a multi-million-pound conspiracy to deal cocaine across region
Last updated 7th Feb 2025
Following an extensive Wiltshire Police investigation, eight people have been jailed for a multi-million-pound conspiracy to supply cocaine across the southwest.
For almost five years, the group – led by brothers Warren and Kelroy Allison – used encrypted communications networks to ship more than 70kg of cocaine across the region, purchasing in bulk and then breaking it down into smaller quantities to distribute onwards.
Following a twelve-week trial at Winchester Crown Court, they were sentenced yesterday (06/02) to a combined 82 years’ imprisonment.
The ringleader, Warren Allison, was jailed for 23 years.
Yesterday (06/02), the eight defendants were sentenced as follows:
• Warren Allison, 36, of Sherford Road, Haydon Wick, Swindon, for two counts of conspiracy to supply cocaine: 23 YEARS
• Kelroy Allison, 41 of Moyle Park, Hilperton, for one count of conspiracy to supply cocaine: 16.5 YEARS
• Richard Cowell, 57, of Godolphin Close, Freshbrook, for one count of conspiracy to supply cocaine: 9 YEARS
• Porcia Densley, 38, of Burnet Close, Melksham, for one count of conspiracy to supply cocaine: 8 YEARS
• Anthony Burke, 34, of Pennyroyal Grove, Bristol, for one count of conspiracy to supply cocaine: 8 YEARS
• Ledian Hoxha, 38, for one count of conspiracy to supply cocaine: 7 YEARS 4 MONTHS
• Pjeter Pisha, 37, for one count of conspiracy to supply cocaine: 6 YEARS 8 MONTHS
• Enid Aliko, 28, for one count of conspiracy to supply cocaine: 4 YEARS
Investigating officer DC Matthew Harvey of SOCU said: “This investigation has systematically broken up a significant operation which was dealing huge amounts of cocaine across not just Wiltshire but the southwest region and beyond.
“The drugs that the Allison brothers, aided by Cowell and Densley, dealt between 2016 and 2020 will have contributed to the social, health and economic impact that cocaine has in the country, such as the associated issues of anti-social behaviour, drug-related violence and acquisitive crime.
“There is also the considerable violence and exploitation which takes place along the supply chain.
“The ringleader behind the organised crime group, Warren Allison, has now been sentenced to more than two decades’ imprisonment, while his brother Kelroy has been jailed for more than 16 years.
“Their wider associates have also been jailed for several years. Intelligence from this operation enabled numerous other targeted arrests, operations and disruptions to be made to many other organised criminals across our region with whom the Allison brothers had been criminally associating with.
“I hope these sentences show that those involved in organised criminal activity are not untouchable or above the law – there are dedicated teams targeting these individuals, and they can be brought to justice.
“I want to highlight the importance of community intelligence in cracking a case like this.
“We know that Warren purchased numerous high value vehicles, including a Lamborghini Huracan, Mercedes C63 AMG and an Audi RS6, with his ill-gotten gains. These extravagant displays of wealth do not go unnoticed by the public, nor the Police.
“If there’s anything which you think could be suspicious, please report it. Any piece of intelligence could be vital.”
