UK Gambling Regulator Backs Police Raids on Illegal Gambling Dens

The Gambling Commission has backed a police operation that seized more than £110,000 in cash, a quantity of gold and sixteen illegal betting terminals from suspected unlicensed gambling venues in Sheffield and Doncaster, with three people arrested.

Officers executed warrants on August 4 and 5, 2026 under two recurring operations, Duxford and Snaresbrook, hitting venues on London Road in Sheffield and Silver Street in Doncaster. According to South Yorkshire Police, the gold was held as bars, coins and jewellery. The three arrests were made on suspicion of immigration offences, possessing a bladed article, and gambling offences.

The raids were a multi-agency effort. Alongside South Yorkshire Police and the Commission, the operation drew in the Yorkshire and Humber Regional Organised Crime Unit, local authority licensing teams and Immigration Enforcement. Inspector Amy Mellor, of the South West Neighbourhood Policing Team in Sheffield, said the activity followed weeks of intelligence development and “is not a ‘one-off'”, with investigations continuing.

Sue Young, the Commission’s Executive Director of Operations, framed the action as a warning to unlicensed operators:

“Illegal gambling isn’t a victimless crime. Unlicensed operators often have links to wider criminal activity, exploit vulnerable people and undermine legitimate regulated businesses. This action should send a clear message – if you’re running an illegal gambling operation we will work with police and other partners to shut you down and ensure you face serious consequences.”

What else the South Yorkshire warrants turned up

The gambling warrants were the focus of the first evening, but police continued executing warrants across Sheffield into the following morning under the wider Duxford banner. That second phase produced three suspected stolen motorbikes from an address in Norton Avenue, more than 2,200 packs of counterfeit tobacco with an estimated value of £11,000 from a property on Glover Road, and a cannabis setup of 279 mature and sapling plants on Chesterfield Road. Four further arrests followed from that activity.

A run of joint raids across England

The South Yorkshire action is the third time in under a month that the Commission has put enforcement staff alongside police in raids on physical illegal gambling venues. On July 21, 2026 the regulator reported raids on two unlicensed gambling dens in Doncaster city centre under the same Operation Snaresbrook banner, where eight people were arrested, just under £9,000 was seized and officers found poker tables, slot machines and account books. On July 29, 2026 it confirmed two arrests after a July 10, 2026 search of a suspected illegal casino on Lower College Street in Bristol, carried out with the local neighbourhood policing team and the South West Regional Organised Crime Unit. The two Bristol suspects, a 36-year-old man and a 40-year-old woman, were released on bail.

Where the Commission’s own powers begin and end

Under its published approach to illegal gambling, providing gambling facilities to consumers in Great Britain without a Commission operating licence is a criminal offence regardless of where in the world the operator is based, and advertising unlawful gambling is an offence in its own right. The Commission can bring criminal prosecutions itself in England and Wales; in Scotland that power sits solely with prosecutors there.

The regulator is also explicit that it announces enforcement steps only at points it judges will not prejudice a future trial, typically when suspects are arrested, warrants executed or charges laid. Its account of the Sheffield and Doncaster raids stops at the seizures and arrests; no charges have been announced.
