A Brighton man has been arrested by police investigating a mail marketing fraud which targeted charities around the country.
The 57-year-old was held on suspicion of fraud and money laundering.
He has been released on police bail while detectives carry out further inquiries.
The Brighton man was one of seven people detained by Wiltshire Police, with four of the seven having been charged with a variety of offences in the past week.
Officers from the Wiltshire force and colleagues from Sussex Police executed warrants in and around Swindon and in Brighton and Hereford in November.
Court proceedings against the four who face charges are due to start in late February.
