An investigation is continuing into the circumstances surrounding the discovery of a man near Ballinamore, Co Leitrim on Tuesday night.
Gardaí say the man was injured and was taken to Mullingar General Hospital, where he is still being treated.
He is believed to be Kevin Michael McGeever who was reported missing by his partner in Gort, Co Galway last June.
It is understood he claims to have been held against his will.
He told the couple who found him that he had been left there by a number of men in a van and did not know where he was.
He had no shoes and was wearing a cap.
Mr McGeever was involved in property development and also had an address in Dublin.
