Five people were arrested today by PSNI detectives in Co Fermanagh investigating deception and allegations of serious fraud involving victims in the Republic and in Britain.
The four women and a man were arrested in the Irvinestown area, a Police Service of Northern Ireland spokesman said.
He said the arrests were part of an ongoing investigation that was likely to continue for some time.
Given the scale of the operation, officers had kept local community representatives informed of what was taking place, he added.
Last week, two men were remanded in custody when they appeared at Enniskillen court charged in connection with the investigation.
They were charged after police raided a series of business premises and homes in the Enniskillen and Irvinestown areas.
The men, Paul Maye (44) from Sallys Wood, Irvinestown, and Dennis McGinley (45) from College Lane, Enniskillen, were charged with obtaining more than £100,000 by deception from a man in the Republic and conspiring to defraud him.
Maye alone faced a series of other changes including dishonestly obtaining over £14,000 from an English businessman by pretending to be someone else and dishonestly obtaining over £38,000 in Social Security benefits he was not entitled to.
