Two men have been sent to prison for a total of 10 years following a police investigation into a series of house burglaries across Swansea and Neath.
Ben Llewellyn, aged 28, and James Green, who is 34, are both from Morriston.
Detectives initially arrested the pair for a burglary in Alltwen after they were disturbed by the lone female occupant of a house. They were then linked to the burglary at the home of Swansea City coach Garry Monk by officers who matched their footwear to forensic evidence at the scene.
Two women were also arrested on suspicion of handling stolen goods – police discovered a photograph of one of them modelling a watch belonging to the partner of Garry Monk.
After Llewellyn and Green were remanded in custody they confessed to committing over 30 burglaries dating back to 2002.
Earlier this month Donna Williams, aged 33, from Brokesby Road in Bonymaen, admitted handling stolen goods from the burglary of Garry Monk’s house, namely a £3,500 Chanel watch, which she bought for £20.
Detective Constable Chris Grey of Swansea CID said, “We have contacted all the victims of these crimes to inform them and in some cases we have been able to return substantial amounts of stolen property to them.”
