University of Limerick student Stephen Cullinan (25) has now been missing for 12 days and his family have appealed for him to phone home.
The Tipperary man from Ballymackey, Nenagh is understood to have left the Castletroy area of Limerick on November 2.
Recent footage has placed Mr Cullinan in at Stephen’s Green in Dublin that evening, where his phone, which has since died, had also been traced to.
Mr Cullinan’s family have made an appeal for him to contact them to let them know that he is safe as there is concern for his well-being.
He is decribed as 5’11’’, of medium build, with short hair and glasses and was last seen wearing a hoodie and jeans.
Mr Cullinan is the son of North Tipperary Irish Farmers Association (IFA) Chairman Tim Cullinan, a group who are also appealing online for help.
Gardaí at Henry Street Garda Station are currently investigating the situation and are appealing to the public for help in establishing Stephen’s location.
Anyone with information should contact Henry Street Garda Station at 061 212 400 or the Garda Confidential Line at 1800-666-111.
