Gardaí are investigating the assault and false imprisonment of an Irish Rail employee in County Laois on Tuesday.
The security officer was approached by a number of men at a rail compound in Kilbricken in Mountrath, just after 5am.
Gardaí say the men assaulted him and locked him in the boot of his car.
The compound is in a rural area and investigators say the make and model of the vehicle the attackers used to make their escape is unknown.
Anyone who may have witnessed any unusual activity in the area is asked to contact Gardai.
