Egyptian in terror probe after Dundalk murder had passed through Northern Ireland

An Egyptian teenager arrested after a violent rampage in which an Asian man was stabbed to death had entered the Republic through Northern Ireland, Garda believe.

The Garda is trawling through two mobile phones recovered from the teenager as they probe whether the attacks are linked to Islamic terrorism.

The killing of the Japanese man in Dundalk has sparked an international investigation, as Garda national units liaise with colleagues in other countries to determine if the arrested man has links to international terror organisations.
