The 38-year-old was found inside the recycling centre in Boleness Road, Wisbech, during a night-time patrol on Tuesday. The man remains in custody following the arrest. The incident comes as proactive patrols have been taking place at industrial sites across Wisbech due to ongoing crime and anti-social behaviour. A spokesman for Cambridgeshire Police said: "The continued offending at this site has a significant impact on those who work and live in the area." People are being urged to contact police if they see anything suspicious in the area.
