A 49-year-old man charged with being the notorious Yorkshire Ripper hoaxer known as Wearside Jack has been refused bail by a judge at Leeds Crown Court.
John Humble is accused of sending the tape between 1978 and 1979
John Humble, of Flodden Road, Ford Estate, Sunderland, is charged with perverting the course of justice.
He is accused of sending letters and a tape to police at the height of the Ripper's reign of terror in the late 1970s which misled their investigation.
Mr Humble will next appear at Leeds Crown Court on 9 January.
The court heard a provisional trial date had been set for 20 February.
Lack of progress
Appearing by video link from Leeds prison, Mr Humble spoke only twice, to confirm his name and that he could hear the judge clearly.
The former labourer is accused of writing two letters and recording an audio tape which were sent to police hunting the killer between 1 March 1978 and 30 June 1979.
He is also accused of sending a third letter to the Daily Mirror newspaper.
The letters taunted police for their lack of progress in catching the Ripper and the tape, which featured a man with a strong Sunderland accent, was played on national television.
Yorkshire Ripper Peter Sutcliffe, from Bradford, now 59, was jailed for life in 1981 for the murder of 13 women.
