Police are investigating after explosive railway detonators were stolen from a railway yard in Frankton, Hamilton.
A police spokesperson said a train at the yard on Kent St was damaged, with several windows broken early on Saturday morning.
A railway detonator is a coin-sized device that is used as a loud warning signal to train drivers.
Detective Senior Sergeant Terri Wilson says because of this, police are urging the public not to touch the items but instead call them straight away.
