DETECTIVES investigating the tragic death of seven-year-old Joe McCafferty in an arson attack 13 years ago may have received some key new leads.

Joe died following a huge fire at his aunt Debbie’s house on Haywood Avenue in Marsh on the night of May 3 1997.

Petrol had been poured through the letterbox and set alight.

The case was featured on last night’s BBC One Crimewatch programme, weeks before what would have been Joe’s 21st birthday.

Det Supt Dave Pervin, of West Yorkshire Police’s homicide and major enquiry team, appeared on the show.

He made a direct appeal to the killer: "I don’t know how you can live with that guilt. But it’s time to stop that guilt and give yourself up now."

On the Crimewatch Update show at 10.45pm, Det Supt Pervin revealed there had been a good response to the appeal.

He said: "We have had several calls into the studio and the incident room, some names of some potential suspects and also had some new information that we’ve not had in the investigation before."

More in tomorrow’s examiner.
