A man who was arrested this week when police raided the Drinsey Nook traveller site near Lincoln has been released under investigation.
Officers swooped onto the site, which was home to the infamous Rooney family, who were jailed as part of a major investigation into modern slavery and fraud offences – dubbed Operation Pottery.
Although members of the gang are serving prison sentences totalling 79 years and seven months for running what was described as a modern-day slavery camp, investigations on the site are still ongoing.
Police carried out the search warrant on the morning of Wednesday, November 1.
They arrested a 26-year-old man on suspicion of participating in organised crime, money laundering and theft.
Lincolnshire Police stated he had been released on the morning of Friday, November 3.
