Gardaí investigating the disappearance of Kenmare man Michael Gaine, say they've undertaken 230 formal inquiries and taken nearly 100 witness statements since the search began.
However, despite extensive enquiries, they say they still don't know happened to Michael on the 20th March last - and this evening, they've renewed their appeal for information.
His family have still had no contact from him, and are extremely concerned for his well-being.
