Concerns are growing for Lifford singer-songwriter Stevie Martin, aka Rainy Boy Sleep, who has not been seen in three weeks.
The 29 year old was last seen three weeks ago in the Derry area, though his car has been found parked at Fanad Lighthouse in Donegal, where a search is currently underway involving the lifeboat services and the Rescue 188 helicopter.
He is described as being 6' tall, with shaven brown hair, facial stubble and a slim build.
Police are appealing for Stevie, or anyone with any information of his whereabouts, to contact the PSNI.
