Gardaí in Co Monaghan are investigating an armed robbery at a post office carried out by two men, one of whom was wearing a Dracula Hallowe'en mask.
It happened at Latton Post Office near Castleblayney at around 5pm yesterday evening.
The pair entered the post office armed with a crow bar and stick and demanded money from the woman on duty.
They are described as being in their late teens or early 20s, and they fled the scene in a silver car with a small amount of money.
Sergeant Ann Friel is from Carrickmacross Garda station said they were very aggressive and prevented the clerk from using the panic alarm, and that they had no distinctive accents to allow her to identify them.
