Detectives investigating reports of fraud involving scammers impersonating police officers have charged three men aged 32, 26 and 25, with false representation.
All three are due to appear at Belfast Magistrates Court on Monday 31 May.
As is normal procedure, all charges will be reviewed by the Public Prosecution Service.
A 30-year-old woman and a 23-year-old man also arrested as part of the ongoing investigation have been released on police bail pending further enquiries.
Police have been granted a court extension for a further 36 hours to question a 28-year-old man, who remains in custody at this time.
