A history nerd who stole a stone from a historic abbey in South Wales returned it after claiming it was giving him ''bad luck''.
The Abbeycwmhir Heritage Trust received the small rock in the post with a letter from the unnamed thief who said he was giving it back because he was haunted by a headless ghost, who he believed to be that of Llywelyn ap Gruffudd, the last native Prince of Wales, who was buried there after his death in 1282.
According to Metro.co.uk, his message read: ''I am so sorry for taking, borrowing, stealing this piece of the old Abbeycwmhir.
''I have been an avid follower of the Welsh Kings and their history and so I took this rock.
''Ever since I have had the most awful luck as if Llewellyn himself was angry with me.
''So I am sending it back. I will not leave my name or address, just a heartfelt sorry from an Australian fan.''
