Four men have been arrested as part of an investigation into the sale and purchase of vintage cars in Co Limerick.

The arrests follow a garda search operation in Rathkeale.

Gardaí said that to date, 20 vehicles are subject of the investigation, with a total value of approximately €360,000.

In many cases the victims have been elderly people.

Gardaí are appealing for more victims from around the country to come forward.

Detective Superintendent Michael Mullen of the Garda National Bureau of Criminal Investigation said: "From enquiries to date, I believe there may be more victims across the country who have been deceived during a transaction involving a vintage or classic car.

"I would like to appeal today, particularly to the elderly community to contact your local Garda Station if you believe that you have been deceived in the purchase/sale of a vintage or classic car in circumstances where either money has not been received or money received far less than that of the value of the car."

Meanwhile, the four men are being held at various garda stations across Limerick.
