A bungled burglary could be the motive behind the murder of a man found dead in his home in Great Yarmouth a week ago.
Mr Colby may have been killed by burglars
Stephen Colby, 47, who lived alone, was found dead with severe head injuries.
Among the many lines of inquiry are being investigated is that burglars could have been involved.
Although nothing was taken from the house in Audley Street, police are investigating claims that Mr Colby, 47, had told people he had recently inherited money from an aunt.
Norfolk Police believe Mr Colby was bludgeoned to death between 2200 BST on Thursday 10 April and 0300 BST on Friday 11 April.
Police have asked anyone who was in the area at the estimated time of the murder to come forward.
Two people arrested in connection with Mr Colby's death and interviewed by detectives have been released on police bail.
