Organised crime group dismantled after multi-year Thames Valley Police probe
Five men linked to an organised crime group operating drug lines across the High Wycombe area have been sentenced following a Thames Valley Police investigation that uncovered Class A and B supply, money laundering and fraud. The court imposed a combined term of 15 years and five months’ imprisonment across the defendants, with further suspended sentences and unpaid work orders for others involved.
Detectives focused on a network that distributed cocaine and cannabis across South Buckinghamshire and channelled criminal proceeds into further offending. The group’s activity was linked by officers to a milkshake shop in Flackwell Heath, with arrests made following coordinated enforcement across addresses in High Wycombe and Slough.
Drugs and assets recovered
Searches yielded significant quantities of drugs and criminal assets. Police reported seizing vehicles, cash and other items worth £324,353, alongside cocaine, cannabis and MDMA valued at £63,490.
| Item seized | Quantity/Value |
|---|---|
| Cocaine | 375.691g |
| Cannabis | 1,908.39g |
| MDMA tablets | 877 |
| Estimated drugs value | £63,490 |
| Assets (cash, vehicles, other) | £324,353 |
Sentences handed down
The five men sentenced in connection with the operation are:
- Oliver Namyslak: jailed for seven years and 10 months for multiple offences, including facilitating and concealing criminal property.
- James Namyslak: sentenced to three years and one month for cocaine-related offences and additional charges.
- Zac Turner, 35: received a one-year suspended sentence and an unpaid work requirement after admitting offences including fraud by false representation.
- Kamil Cole (no fixed abode): given a suspended sentence with unpaid work; pleas included possession of drugs with intent to supply.
- Jammal Cole (no fixed abode): also received a suspended sentence and unpaid work, with pleas including possession with intent to supply.
Thames Valley Police said the case reflects extensive work to unpick the group’s finances and drug distribution, with searches spanning multiple addresses.
“This investigation has led to a total of fifteen years and five months imprisonment for these five men, and is a big testament to the officers who worked hard in compiling years of evidence, to finally seek justice.”
Detective Sergeant Joe Windsor praised the officers who gathered the case material over an extended period. The lead investigator, Detective Chief Inspector Jonathan Chandler, underscored the role of community intelligence in disrupting drug harm across neighbourhoods.
Impact on communities and ongoing enforcement
The case will resonate in and around High Wycombe, where residents have raised concerns about open drug dealing and associated disorder. By targeting a local retail outlet as an alleged hub for offending, officers sought to cut off a gateway between street-level dealing and the wider supply chain.
While three defendants were imprisoned immediately, the use of suspended sentences and unpaid work for others indicates the court’s approach to lower-level roles within the network and offences that fell short of immediate custody thresholds. The overall package includes the forfeiture of assets, intended to strip criminal profits and limit the group’s ability to re-establish operations.
What the figures tell us
Beyond individual terms of imprisonment, the scale of asset recovery — over £324,000 — suggests systematic reinvestment of illicit proceeds, with the additional seizure of Class A and B substances pointing to a mixed model of supply. The police action in High Wycombe and Slough highlights cross-border movements within the Thames Valley area, where local retail premises can mask serious criminality.
Thames Valley Police has said the outcome should reassure residents that intelligence about suspected drug lines helps inform targeted operations. Chandler emphasised the importance of public reporting to disrupt distribution and reduce related offences, including fraud used to support further criminal activity.
