GARDAÍ HAVE ARRESTED three youths, all in their late teens, in connection with a public order incident on a train this evening.
The incident occurred on the 5.55pm service from Heuston to Newbridge.
It is understood that a fight broke out after a number of people travelling on the train were accusing of attempting to steal from others, and that one person was assaulted.
Several passengers called 999, but did not inform the driver using the on-board emergency phone system.
The train continued to Sallins, where those involved in the fight dismounted.
However, gardaí arrested one person in connection with the incident as they left the station shortly after 6pm, and two more were arrested a short time later in Naas town.
Irish Rail will be assisting gardaí with their investigations by supplying CCTV footage from the train.
Gardaí at Naas are continuing their investigations.
