Armed gardaí have rescued a suspected kidnap victim being held at gunpoint and arrested four men on the motorway outside Dublin.

On foot of information received from the Police Service of Northern Ireland (PSNI) in relation to a report of kidnap in Belfast, gardaí say they instigated a "managed-containment operation" in Dublin on Thursday evening.
