THE search for Alice Byrne has been extended in a Scotland-wide appeal one week on from her disappearance.

Volunteers in Glasgow, Dundee and Perth were distributing posters of Alice on Friday in a bid to 28-year-old who has been missing since New Year's Day.

Efforts were also moved up by Police Scotland today as the air force's drone flew above Portobello Beach - the area where Alice went to celebrate Hogmanay. 

A group set up on Facebook in the search for Alice has attracted around 2,500 members in just a matter of days. 

It aims to mass distribute posters across Scotland and wider in the search for Alice.

Alice was reported missing in the early hours of New Year’s Day. It is understood that she had planned on attending a beach party near the Portobello area to bring in the bells.

In an update, she was seen leaving a house party on the morning of January 1 around 10am on Marlborough Street in Portobello.

But there has been no sighting of her since.

Rich Howells, of the 'Find Alice Bryne' group told the Herald: "There has been a marked increase in police activity within Portobello since we started our group and activities.

"We have been overwhelmed by the community response, and it has been incredible to channel everyone's energy into doing something positive at this incredibly challenging time."

Police first issued an appeal on January 3 as information about her disappearance spreads across various social media platforms.

They released an updated image of her on January 5.

Alice's family have also spoken out during the appeal - including her two brothers - asking the public to come forward if they have any information.

Chief Inspector Kieran Dougal from Craigmillar Police station said: “Alice is known to frequent the Portobello and New Hailes areas of Edinburgh.

“Since she was reported missing, officers have been carrying out extensive searches and enquiries in these areas. Local officers led by specialist search advisors have been assisted by resources including the air support unit, police dogs and our marine unit.

HeraldScotland:

“Officers will continue to speak to people who know her and who live in the local community. Searches are continuing throughout the area, and we would also ask local residents to check their outbuildings and sheds, as well as urging anyone with any information on Alice’s whereabouts to get in touch as soon as possible.”

“This is an upsetting time for Alice’s family who are extremely concerned that she has not been in contact with them since Saturday. This is completely out of character for her.

“I would again urge anyone who has seen Alice since Saturday morning, or anyone with information on her whereabouts to contact us as soon as possible. If Alice reads this appeal, I urge her to phone her family, friends or the Police. Contact 101 quoting reference 0647 of 2 January.”
