Armed gardaí carried out a containment operation on the M50 last night after getting information from the PSNI about a suspected kidnapping in Belfast.
A car was intercepted at Junction 4 Ballymun shortly before 10pm.
Four men were arrested at the scene and a firearm was recovered from the vehicle.
A fifth man, who was also in the car and who was reported missing from Belfast, was found safe and well.
