Organised gangs in London are drugging revellers on nights out to steal their luxury watches in a disturbing new crimewave. Victims are given drugs such as rohypnol and GHB, often used in sexual offending, to incapacitate them before thieves steal Rolex watches valued at over £10,000, along with other valuables. This trend has escalated in recent months, adding to the capital's existing problem of moped-enabled watch snatchings.
Warning from Former Detective
Former DCI Dave McKelvey, now running private security firm My Local Bobby, issued a stark warning: "We're seeing a very disturbing pattern where spiking is being used as a method of robbery. This is a relatively new crimewave which needs to be stopped. It's very dangerous." He noted that offenders specifically target victims, incapacitate them, and steal watches, phones, and wallets. While incidents have concentrated in central London, McKelvey expects the crime to spread across the country.
Dangers of Rohypnol and GHB
Rohypnol, a Class C drug, depresses the nervous system, causing severe sedation, memory loss, motor impairment, confusion, aggression, and loss of muscle and impulse control. GHB, a Class B drug, can lead to overdosing, seizures, severe aggression, psychosis, lowered inhibitions, and organ damage. McKelvey also warned of cases where victims believe they are buying cocaine but are instead given a spiking drug, leaving them vulnerable to theft by the dealer.
Police Response
A Metropolitan Police spokesperson stated: "Spiking is an invasive and distressing crime that is often difficult to investigate due to the limited window to secure evidence. The Met has invested significantly in tackling spiking, leading on new detection technology, and working with partners to strengthen prevention in nightlife settings." From January to December 2025, positive outcomes including charges increased by 132% compared to the previous year. The force is also cracking down on mobile phone theft, with offences down by 13,000 and overall theft in London falling by 21%.
McKelvey urged revellers to remain vigilant: "People, more than ever, need to be very aware of their surroundings."
