Ontario Provincial Police say no charges will be laid in the disclosure of Toronto police documents concerning NDP Leader Jack Layton.
Sun TV reported in the closing days of the federal election campaign that Mr. Layton was in a Toronto massage parlour when police raided it in 1996.
Mr. Layton, who was neither arrested nor charged, called the report a smear campaign.
The information was attributed to police notes taken at the time of the incident, and Toronto Police asked the provincial police force to investigate.
Police said on Thursday that the incident was investigated by Det. Insp. Mike Bickerton, who concluded criminal charges would not be laid.
However, a provincial police spokesman said the investigation resulted in a number of police notebooks that were in the possession of a former Toronto officer being returned to the force.
After the Sun TV story broke, a lawyer for the NDP said in a statement that Mr. Layton had obtained a massage from a massage therapist, but had no knowledge the location may have been used for illicit purposes.
Brian Iler's statement added that police told Mr. Layton he did nothing wrong, but that the location was questionable. It said Mr. Layton gave police his name and address and nothing further happened.
