GARDAÍ HAVE confirmed a new sighting of Monica Riordan, who went missing in Dublin’s city centre on 20 December.

The 39-year-old was captured on CCTV footage in the Grand Canal Street area at around 3pm.

Gardaí say that they now have a confirmed sighting of Riordan on Pearse Street at the Macken Street junction at around 5pm that day.

She had walked along Macken Street from under the railway bridge towards the junction with Pearse Street and appeared to be disoriented and confused at the time.

Riordan is described as being of average height, slim build and with shoulder-length blonde hair. When last seen, she was wearing a hooded long grey coat, dark jeans and grey or white trainers.

Her friends and colleagues have set up a Facebook page to raise awareness about the disappearance and have been distributing posters in a renewed appeal for information.

Gardaí are appealing to anyone who was in the Macken Street, Pearse Street or Grand Canal Street area between 4.30pm and 6pm on Tuesday to contact Pearse Street Garda Station on 01 666 9000, the Garda Confidential Line 1800 666 111, or any garda station.
