A Swansea man has been jailed for his role in a major organised crime gang that pumped drugs into communities across south Wales.
Bradley Williams, 38, from Swansea, was sentenced to five years and nine months in prison after pleading guilty to multiple drug offences.
He was part of a wider network supplying cocaine, cannabis and ketamine across the region — in what police described as a large-scale operation causing “misery and harm” to local communities.
The gang was brought down following a major investigation led by Tarian, the regional organised crime unit for southern Wales.
Major operation targets drug network
The investigation — known as Operation Allegro — targeted a sophisticated drugs network operating across south Wales and into southwest England.
Officers worked alongside Gwent Police and Gloucestershire Constabulary to dismantle the group, which was led by Gloucestershire-based Danny Tomlin.
The gang was responsible for supplying wholesale quantities of Class A drugs, including cocaine, as well as cannabis to a wide customer base.
Their operation stretched into communities across Swansea Bay and beyond.
Swansea link to wider criminal network
Williams played a key role in the network, admitting conspiracy to supply cannabis, offering to supply cocaine and ketamine, and possession of criminal property.
His involvement highlights how organised crime networks often rely on local figures to distribute drugs into towns and communities across the region.
Police say these operations fuel wider issues including addiction, violence and exploitation.
Cannabis factories uncovered
As part of the investigation, officers uncovered two sophisticated cannabis factories hidden inside residential properties.
The sites — located in Blackwood and Trebanog — were being used to produce large quantities of cannabis for distribution.
The discovery underlined the scale and organisation of the gang’s activities.
Early morning raids bring gang down
The network was dismantled following coordinated police raids across multiple locations in July 2025.
Officers executed a series of warrants over two days, arresting those involved and gathering key evidence.
Seven of the nine defendants later admitted their roles before or during trial.

Other key members from Newport and Gloucestershire received sentences ranging from several months to six years.
In total, the nine members of the group were handed combined sentences of more than 43 years behind bars.
Police: ‘Misery and harm’ caused to communities
Detective Inspector Vinnie Easton said the group had been driven by profit at the expense of local people.
He said: “This was a large-scale, complex investigation into an organised crime group who sought to profit from the misery and harm they brought to our communities.”
He added that the sentences should reassure the public that action is being taken against drug supply networks.
Impact felt across Swansea Bay
While the gang operated across multiple areas, cases like this highlight the impact organised crime has on communities in Swansea and across the wider region.
Police say tackling drug supply remains a priority, with networks like this often linked to wider criminal activity.
Residents are being urged to report concerns about suspected drug dealing.
Public urged to come forward
Anyone with information about drug supply can contact police via 101 or report anonymously through Crimestoppers.
Officers say intelligence from the public plays a key role in building cases against organised crime groups.
