Police and the family of missing person, 29 year old Stephen Martin, are becoming increasingly concerned for his well-being.
Stephen was last seen in the Derry area approximately 3 weeks ago.
He is described as being 6’ tall, of slim build, with brown coloured shaven hair and facial stubble.
It is believed that Stephen has travelled to Donegal and his Audi car has been discovered parked at Fanad Lighthouse in Donegal.
Police are appealing for Stephen, or anyone who knows of his whereabouts, to make contact with police or his family on 101.
