A man arrested in Blanchardstown, Dublin, early yesterday has been taken to Monaghan Garda station to be questioned by the team investigating the Omagh bombing. He joins three other men from the Dundalk area who were arrested on Tuesday morning and also taken to Monaghan. All four, it is believed, are being questioned about the theft of a Vauxhall Cavalier car stolen in Carrickmacross, Co Monaghan, two nights before it was used in the bombing.
