Gardai have initiated a Child Rescue Ireland (CRI) Alert in their search for a missing 14-year-old girl, saying they have concerns that there is ”an immediate and serious risk to her health or welfare”.

Svetlana Murphy left her home on the Coast Road in Blackrock, Co Louth at around 4 pm on Monday.

She is described as 5 foot 1 inch in height with a slim build. She has brown hair and brown eyes.

At the time she went missing, Svetlana was wearing navy tracksuit bottoms with a red and white stripe on the leg, a black zipped top, and black runners.

Svetlana is in the company of 18-year-old Nojus Maculevicius, who is described as being 6 foot in height with a slim build.

He has dark brown hair and he is clean shaven. He was wearing dark grey Snickers work trousers and a black Snickers top. He may also have been wearing a khaki green hoody, and either black boots or Adidas runners.

They are travelling in a silver Hyundai Veloster car, with registration number 132-D-13518.

Gardaí are satisfied that Svetlana and Nojus travelled from Blackrock, Co. Louth to Newry, Co. Down on Monday and were seen there at approximately 7 pm that night.

Gardaí are satisfied the Hyundai Veloster car was in the greater Belfast area at 5.35 pm on Wednesday evening.

The public is urged not to approach those involved but instead immediately contact gardaí on 999 or 112 with as much information as possible.

Gardaí believe that Svetlana and Nojus have not left the island of Ireland and that the Hyundai Velostar car is still in Northern Ireland.

This is not understood to be a ‘stranger abduction’ and the 18-year-old man is known to 14-year-old Svetlana.

“Svetlana is 14, she has been missing since Monday but obviously over the past few days our concerns have increased to where we have issued a Child Rescue Ireland Alert,” Superintendent Liam Geraghty of the Garda Press Office said.

“So we are looking for Svetlana to contact us or the male she is with, Nojus, to contact us or anyone who sees the car.

“We certainly believe that they are still on the island of Ireland, there is nothing to indicate that they have left at this stage.

“The chances are and we believe the car is still in Northern Ireland, so anyone [who sees it] should contact either straightforward 999 or 112 or in the North the Police Service Northern Ireland (PSNI), they are working with us on this and they will pass on the information.”
