The victim suffered a bleed on the brain and developed epilepsy due to Powell’s actions
A Welsh man who stole part of a £3m Viking hoard has been jailed for a “brutal” attack on a friend over stolen gold. George Powell, 45, from Pill in Newport, was jailed in 2019 for his part in stealing 300 Viking coins and gold jewellery he found in a field in Herefordshire in 2015.
It is regarded as one of the biggest treasure finds in British history. In January 2025 Powell went on the run after he failed to repay £600,000 – his share of the hoard.
Police did not find him until nine months later, in October 2025, when he was arrested and charged with GBH following an incident in Paignton, Devon. Don’t miss a court report by signing up to our crime newsletter here
The incident saw Powell’s friend, Lewis Prosser, sustain serious injuries including a bleed on the brain.
Powell previously pleaded guilty to grievous bodily harm and appeared at Exeter Crown Court to be sentenced for the offence on Monday. He appeared via a link from custody at Exeter HMP.
Prosecuting, Michael Brown, told the court how on October 16, 2025, Powell invited Mr Prosser to stay with him at a caravan at Hoburne holiday park on Grange Road, Paignton. Powell had previously booked into it with a false name to conceal his true identity.
Mr Brown said Mr Prosser recalls that their first evening was uneventful, that they shared some drinks and had a “good night”. “The after his recollection of the events and timeline is poor,” Mr Brown said.
The prosecution had been able to establish that in the early hours of October 18 the victim had booked a taxi with the intention of leaving, after it appeared that a disagreement had taken place.
Mr Prosser told the police that Powell had wanted to carry on drinking, and he hadn’t. However in an initial statement he told officers that the argument arose because Powell had taken gold items and jewellery from him. Subsequently items that matched this description were found.
Mr Brown told the court how Mr Prosser got to Paignton train station but was unable to catch a train due to the time, and so had returned to the caravan to sleep.
It was heard how the victim awoke to Powell on top of him and hitting him with two weapons: a knife and a trunch baton.
It is the prosecution’s case that Powell was hitting Mr Prosser on his head with the knife, with the victim recalling feeling a sharp pain.
Mr Brown described the attack as “prolonged, sustained and repeated”, resulting in “extensive blood at the scene”.
Mr Prosser managed to get to another caravan, it was heard. The occupants of which called the emergency services, with paramedics and police officers arriving on the scene.
Mr Prosser received first aid at the scene and was “in and out of consciousness”. He was in hospital for 10 days, with his injuries identified as: a bleed on the brian, a fractured jaw, a fractured ankle, a full-thickness head wound, bruising and swelling, reduced hearing and reduced and double vision. It was heard how the victim also developed epilepsy as a result of the incident.
In a victim impact statement Mr Prosser described how he has been left with poor short term memory and balance issues. He described having members of his family helping him with basic tasks and checking he takes his medication correctly. He has also been diagnosed with post-traumatic stress disorder and has made multiple attempts to end his own life, he said.
Powell was arrested on October 21, arguing that he attacked Mr Prosser in “self-defence”. He has 23 convictions for 60 offences.
Powell’s defence barrister told the court that this incident is not part of “a pattern of offending”. He added that his client “wholeheartedly regrets” the incident and “has got the capacity to not come back before the courts”. He said Powell has Crohn’s disease which has impacted negatively on his time in custody.
Addressing Powell, Judge Stephen Climie, called the incident a “brutal attack”. He sentenced him to 20 months in prison. This will be added to his current sentence of five years and three months for failing to repay the money.
