Record haul of unlicensed weight loss drugs seized at Northampton estate

Two men have been arrested after officers from the Medicines and Healthcare products Regulatory Agency (MHRA) raided a country estate near Northampton, seizing around 12,000 doses of unlicensed weight loss medicines — the largest such seizure the agency has ever carried out.

The operation, conducted on the night of 28 May 2026 with the support of Northamptonshire Police, resulted in the arrest of two male suspects, both aged 29, on suspicion of offences under the Human Medicines Regulations 2012. Enquiries are ongoing.

Gov.uk reports that the property is believed to have served as a large-scale facility used to manufacture, assemble, and distribute unlicensed weight loss medicines — including retatrutide and tirzepatide — as well as peptide products. Officers also recovered substantial quantities of packaging materials and substances believed to have been used in the illicit production of those products.

Andy Morling, Head of the MHRA's Criminal Enforcement Unit, said the operation demonstrated the agency's determination to pursue those exploiting public health for profit. "Medicines regulation isn't discretionary — it exists to protect people," Morling said. "In addition to disrupting an organised criminal group, I'm confident that dismantling this illicit production facility will have prevented significant public harm."

Morling added that the agency would continue to target criminal networks seeking to bypass medicine safety protections, and expressed his gratitude to Northamptonshire Police for their support.

The raid is the latest in a series of enforcement actions carried out by the MHRA's Criminal Enforcement Unit in recent months, during which several criminal networks have been dismantled and significant quantities of unlicensed and potentially dangerous products removed from circulation.

The MHRA's Criminal Enforcement Unit leads the agency's response to medicines crime, using intelligence analysis, covert techniques, online disruption, and asset recovery, alongside close cooperation with UK and overseas law enforcement. The MHRA is an executive agency of the Department of Health and Social Care, responsible for regulating all medicines and medical devices in the UK.

Anyone who suspects they are experiencing a side effect from a medicine is advised to speak to their doctor, pharmacist, or nurse, and to report it via the MHRA Yellow Card scheme.
