A 65-year-old man has been convicted of stabbing another man in a “brutal” attack outside a Wiltshire supermarket.

Luciano Marenghi was found guilty of wounding with intent to cause grievous bodily harm following a dispute outside the Pewsey Co-op store, on September 4, 2023.

The 65-year-old repeatedly stabbed his victim, a man in his 30s, during the incident.

Witnesses described an attack committed with enough force to bend the blade out of shape.

Marenghi denied the charge, claiming he acted in self-defence.

During a trial at Salisbury Crown Court, prosecutors used eyewitness testimony and CCTV evidence to argue the attack was “wholly disproportionate.”

Police and prosecutors praised members of the public who restrained Marenghi and tended to the victim’s injuries before officers arrived.

Simon Clark, Senior Crown Prosecutor with CPS Wessex, said: “This was a shocking attack which will have undoubtedly disturbed the local community.

“Marenghi’s attack was brutal and the victim in this case was lucky to have not been more seriously hurt.

“I hope today's conviction sends a clear message to anyone who arms themselves with a knife that such behaviour will not be tolerated in our society.

“I’d also like to pay tribute to the brave members of the public who assisted the victim and police during this incident.”

Marenghi will be sentenced at a later date.
