A 16-year-old boy is being questioned at Henry Street garda station about a tiger kidnapping on the outskirts of Limerick city.
The alarm was raised in the early hours of Monday morning - a number of hours after a 19-year-old man was abducted from his home on the outskirts of the city.
The man, whose relatives run a post office in the city, was threatened at gunpoint before being driven around in a 4x4 vehicle for around two hours.
It is understood the victim was told to contact his relatives and ask for a ransom during the ordeal.
The teenager was arrested a short time after gardai were alerted to a suspicious vehicle in the Donoughmore area at around 1.30am.
The kidnapping victim, who was not seriously injured, was located after the vehicle was stopped.
Investigating gardai say at least two other young men were involved in the incident.
Henry Street Gardai can be contacted at (061) 212400.
