Investigators uncovered more than 12,000 doses of illegal weight-loss injections during a raid on a suspected black-market drug factory operating within a £2.2 million Georgian country house in Northamptonshire. The property, Moulton Grange, was searched on May 28 as part of an ongoing investigation into unlicensed medicines.

Officers from the Medicines and Healthcare products Regulatory Agency (MHRA) arrested two 29-year-old men in connection with the operation; they were later released. The MHRA, which described the raid as the UK's largest seizure of unlicensed weight-loss injections, is targeting what it believes to be an "organized criminal group."

Moulton Grange, which boasts 28 acres of grounds, is also known as a venue for luxury weddings and corporate events. Online reviews describe it as a "perfect venue" and "simply magical."

However, the MHRA suspects the estate was being used as a "large-scale facility to manufacture, assemble, and distribute unlicensed weight loss medicines, including retatrutide and tirzepatide, as well as peptide products." Tirzepatide is the active ingredient in Mounjaro, and retatrutide is an experimental treatment currently undergoing clinical trials.

Images from the raid showed numerous boxes and containers filled with injections scattered across cluttered rooms within the property. The investigation also revealed that the products were branded 'Alluvi,' matching a trademark application filed in April 2026 by a company based in Northampton. Investigators noted that this was the first time they had uncovered an operation producing drugs marketed under its own brand.

Andy Morling, head of the MHRA's Criminal Enforcement Unit, commented that the packaging discovered at the raid site appeared "sophisticated" and "authentic-looking." He emphasized the importance of medicine regulation for public protection and stated that dismantling this facility would prevent significant public harm.

This is the second MHRA operation in Northamptonshire in recent months related to the alleged production of illegal weight-loss injections. A previous raid in October 2025 yielded fewer unlicensed drugs.

Moulton Grange, constructed in the late 18th and early 19th centuries, is a Grade II-listed building. It was last sold for £2.2 million in 2017. The property is owned by Faiz and Rashda Hameed, who are also directors of the property management company Moulton Grange Limited. In 2014, Faiz Hameed was fined £312,000 by Northampton Magistrates' Court for violations related to housing standards in properties he owned.
