A man has been arrested after police raided the Drinsey Nook traveller site near Lincoln.
The site was home to members of the infamous Rooney family who were jailed as part of a major investigation into modern slavery and fraud offences – dubbed Operation Pottery.
Police said that although members of the gang were serving prison sentences totalling 79 years and seven months for running what was described as a modern-day slavery camp, investigations are still ongoing.
Police carried out a search warrant on the morning of Wednesday, November 1 at Drinsey Nook.
A 26-year-old man was arrested on suspicion of participating in organised crime, money laundering and theft.
A spokesperson for Lincolnshire Police said: “Although defendants are now serving sentences, we are now investigating possible offences of fraud, money laundering and proceeds of crime.
“We will update on this investigation when we are in a position to do so.
“Officers, who remain on site, are being assisted by Nottinghamshire and Leicestershire Police, the Department for Work and Pensions, West Lindsey District Council and Newark and Sherwood Council.”
