Wrench attack in Bristol: 16 and a half years in prison for 3 men who targeted an individual’s cryptos

Adjustable wrench against cryptocurrency, English version. The webcomic xkcd summed up the problem in 2009: why break an encryption when all you have to do is hit its owner? Three men tried to apply the recipe in a Bristol home last May. They failed, and British justice has just given them a cumulative 16 and a half years in prison.

The scenario has become sadly familiar for French readers, with 41 crypto-kidnappings recorded in France between January and mid-April 2026. The outcome of the Bristol affair, however, is due to the intervention of a teenage girl.

A trio aged 30 to 37 broke into the home of a Bristol resident in the middle of the night to force him to give up his cryptos.

The alert given by the owner's younger sister led to the immediate arrest of the attackers.

Found guilty, they will serve between five and six years behind bars.

Chainalysis counts 46 physical attacks of this type on the planet between January and June 2026.

The scene takes place in the early hours of May 15, 2026. Three men force entry into a home in Bristol, in the southwest of England, and attack its occupant. They demand that he transfer them a large sum in cryptocurrencies. The victim received a blow to the head, and the injury required hospital treatment.

The plan quickly goes off the rails. The victim's teenage sister managed to notify the police, who arrested the three intruders at the scene. No transfer took place.

The term comes from xkcd: the “wrench attack”, or wrench attack, consists of physically forcing a holder to empty their wallet rather than hacking their keys.

The three men pleaded guilty to aggravated burglary at the August hearing. English law reserves this qualification for intrusions committed with a weapon or similar object.

Bristol Crown Court fixed the sentences on October 15. Terroll Paul, 31, received six years in prison. Pierre Madzou, 30, takes five and a half years. Mohamed Samagassi, 37, is sentenced to five years. The statement from Avon and Somerset Police said Paul and Madzou live in Barking, east London. Samagassi has no fixed address.

Read at the hearing, the victim's statement described a transformed man. Once jovial and talkative, today he says he is “constantly scared” and always on guard. Gemma Childs, the officer in charge of the case, praises the young girl’s composure. His appeal led to the arrest and spared his brother from further violence.

The English courts continue with this type of case. Three teenagers from Sheffield were sentenced in February 2026 to a total of 16 years in detention. Disguised as delivery men, in June 2024 they stole the equivalent of $4.3 million in crypto from a resident of the London district of Hoxton. In May, four men were sentenced to up to six and a half years for kidnapping a City employee after a night out in Shoreditch in July 2025. It was Coinbase who raised the alarm.

Chainalysis has recorded 46 physical attacks against crypto holders worldwide in the first half of 2026, compared to 40 a year earlier. The loot exceeds 30 million dollars. But only 26% of these attacks resulted in payment, compared to 49% in 2025. The Bristol trio swells the column of failures.

France remains the European epicenter. The same report counts 30 public incidents there at mid-year, more than in all of 2025 (19). In July, Interior Minister Laurent Nuñez reported 77 kidnappings, extortions or attempts, compared to 45 the previous year. Chainalysis links part of this surge to data leaks, including the alleged sale of tax information by a public official.
