Gardaí searching for Blathnaid Timothy, who has been missing for almost three weeks, have re-issued an appeal for information.

The 33-year-old works in the Irish Financial Services Centre in Dublin and lives at Camden Street in the city.

CCTV images from Tuesday 14 December show her using a National Irish Bank ATM at Sir John Rogerson's Quay in Dublin at about 8pm.

Other CCTV images show her getting into a dark-coloured taxi there.

Gardaí are asking the taxi driver to come forward - they say he may have missed earlier appeals if he was away on holidays.

Ms Timothy was wearing a three-quarter length black wool coat, possibly grey jeans and a scarf tied around her neck -possibly red and black.

She is described as 5'6'' in height, with medium-length dark brown hair, of thin build with a pale complexion.

Anyone with information should contact Harcourt Street Garda Station on 01-6669500.
