A man who carried out a run of thefts from shops in Abergavenny over just three days has been sent to prison.

Guy Seabourne, 40, was jailed for two months (eight weeks) at Newport Magistrates’ Court on Friday 6 November 2026, having admitted six counts of theft.

What was taken

Between Monday 2 November and Wednesday 4 November, Seabourne stole from four stores in the Monmouthshire town. The items he took included:

  • alcohol
  • food
  • a bobble hat
  • washing pods

In court

Seabourne, whose address is Mounton Road in Chepstow, entered his guilty pleas at the same hearing at which he was sentenced. Gwent Police described him as a prolific offender, and he was on licence when he committed the thefts.

What police said

PC Aled Thompson, the force’s neighbourhood ward manager for Abergavenny, said:

“Theft is not a victimless crime and we know it is exceptionally dispiriting for retailers and staff to be targeted in this way by repeat offenders like Seabourne.

“Seabourne was on licence at the time he committed these offences and we will continue to pursue thieves like him who case harm to our communities and make life a misery for business owners and staff in Abergavenny and beyond.

“Creating safer town centres is a key part of the Neighbourhood Policing Guarantee.

“Tackling retail crime cannot be achieved by policing alone. It depends on all partners playing their part by reporting incidents promptly, sharing quality evidence, and supporting local problem-solving activity.

“While part of our work to tackle shoplifting in Abergavenny includes providing security and crime prevention advice to businesses, it is crucial that anyone who is affected by theft, reports it to us.

“By working together, we can do even more to protect retail workers, support businesses, and make our communities safer.”
