Lincolnshire Police arrested an eighth person in connection with ongoing modern slavery raids in Lincoln, while all seven people initially arrested have been released.
The further 28-year-old man was arrested in the morning of Wednesday, September 24, in connection with slavery offences and is due to be questioned by officers.
He, alongside the seven others, was arrested as police investigated allegations of modern slavery at five Lincoln locations.
Seven people were rescued during raids, dubbed Operation Pottery, on Monday, September 22.
Of the seven people arrested during the raids, four men, aged between 21 and 52, and one 53-year-old woman were bailed.
An 18-year-old man who was arrested on suspicion of obstruction has also been released with no further action.
The seventh person to be released following the raids was a 28-year-old man.
The people rescued during the raids are now in the process of being seen by medical professionals for health assessments and will be interviewed by Lincolnshire Police officers as witnesses at a later date.
Modern slavery is where both UK residents and those brought from overseas, are forced to illegally work against their will in many different sectors, including brothels, cannabis farms, nail bars and agriculture.
