Twelve men have been jailed following an investigation into an organised crime group (OCG) based in Swansea.

Operation Shelduck, conducted by the Swansea, Neath and Port Talbot Organised Crime Team to investigate the supply of Class A and B drugs, was commenced following the arrest of Abdul Mozid for an unrelated drugs offence in November 2023.

A mobile phone in Mozid’s possession at the time of his arrest contained evidence to show he was the principal member of a large-scale conspiracy to supply controlled drugs including cocaine, MDMA, cannabis and ketamine.

Mozid was directing the large-scale supply of Class A and B drugs not only into Swansea, but also areas including Pyle, Cardiff, Carmarthen and Bristol, with evidence showing a substantial supply network.

The OCG utilised several encrypted chat platforms including Telegram, Signal, WhatsApp and Snapchat. These platforms allow the user to utilise “handles” or usernames instead of providing personal information. By using these sites, members of the OCG were attempting to evade law enforcement by ensuring their anonymity. However, nine men were able to be attributed to usernames which had engaged in messaging regarding the OCG’s drug supply.

Some of the men – Ruhel Chowdhury, Mohammed Hanif Miah, Moinul Islam and Mohammed Robbani – were identified as working alongside Mozid in the OCG’s operation. Other men – Levi Edwards, Bryan Clark, Mohammed Rahman and Diamant Halili – were identified as “running” or delivering drugs for the OCG.

Several bulk customers were also identified has having received substantial quantities of controlled drugs from the OCG. These – Mohammed Jubair Uddin, Abul Hushain and Jamshed Khan – were arrested separately to the main nine defendants and have already been sentenced due to entering guilty pleas. All were proven to be large scale customers of the OCG who were in turn running their own drug supply operations.

A premises on Finsbury Terrace, Brynmill, Swansea was being used by the OCG as a ‘safe house’. Substantial quantities of Class A and B drugs as well as cash were found during a warrant at the address:

Over £45,000 cash seized
£44,000 cash restrained (POCA)

31.5 grams of crack cocaine
228 grams of MDMA powder
970 MDMA tablets
2.3 kilograms of ketamine
8 kilograms of cannabis

Abdul Mozid – 10 years, eight months’ imprisonment
Mohammed Hanif Miah – 10 years, six months’ imprisonment
Ruhel Chowdhury – nine years’ imprisonment
Moinul Islam – seven years’ imprisonment
Mohammed Robbani – four years, five months’ imprisonment
Diamant Halili – four years, nine months’ imprisonment

The following three defendants were shown to be bulk customers of the OCG and running their own drug supply operation and have already been sentenced:

Jamshed Khan – three years’ imprisonment
Mohammed Jubair Uddin – four years’ imprisonment
Abul Hushain– six years, five months’ imprisonment and 62-month driving ban

Detective Sergeant Ian Foster said:

“Operation Shelduck has seen a deeply complex investigation into a group of men who cared about nothing other than profiting from the supply of drugs into our communities.
“Like many others before them who have thought similarly, this has not paid off for them, and they are now embarking on significant terms in prison.
“I would like to acknowledge the work of the Scene of Crime Officers (SOCOs), the Joint Scientific Investigation Unit (JSIU), the COMU for all Comms applications, the analyst and the financial investigator.
“Also, the work of the Neighbourhood Policing Team, the Territorial Support Team, the Organised Crime Team and the Specials for the day of the warrants was of utmost importance to the investigation.
“I would also like to highlight the work of the officer in case, PC Owen Smith, who was instrumental in securing these sentences for all those involved in this OCG.”
