Three men have been arrested in connection with online dating scams.
It's understood one of the victims was convinced to transfer large amounts of cash, having met with fraudsters via a dating site.
The arrests in West Dublin and Navan in Co. Meath follow complaints of suspected romance and investment fraud.
Officers believe one of the victims in the case was convinced to transfer large sums of cash to accounts in Ireland, Turkey, Dubai and Vietnam over a nine month period.
Gardaí made three arrests today during search operations, and a number of devices have been seized.
They say they expect numerous injured parties from all over the world will now be identified, and they're encouraging victims of this type of fraud to report incidents to local Gardaí.
The men arrested today can be held for up to seven days.
