Gardaí have appealed for information about a German woman who has not been seen for two days.
A Garda spokesman said they are extremely concerned for the safety of Ms Betina Poeschel (28).
Ms Poeschel was due to fly home to Germany yesterday but failed to return from a visit to Newgrange, Co Meath.
Her father and sister, who flew into Dublin, have appealed for help in finding her.
