An Irishman has died after he stabbed three people in a violent spree in northern Germany.
One of his victims, a taxi driver aged in his 50s, is in a serious condition in hospital.
The Irishman, who was aged in his 20s, hailed a cab in Holland and asked to be driven over the border to Germany, where he stabbed the taxi driver in the city of Aachen.
Shortly afterwards, he stabbed another man, before hailing a taxi and asking to be taken to Cologne.
The taxi driver managed to get the man to leave his taxi, which he did on a lay-by, where he stabbed a Lithuanian truck driver before running onto the motorway, where he was hit by a car and killed.
Gardaí have confirmed they are liaising with German authorities after the death of an Irish national in Cologne.
They say they were notified of the man's death yesterday by Interpol.
The Department of Foreign Affairs are also offering assistance to the man's family.
