New leads after Huddersfield arson death TV appeal
Detectives are following new leads after a television appeal for information about the death of a boy in an arson attack 13 years ago.
Joe McCafferty, seven, died after petrol was poured through the letterbox of a house on Haywood Avenue in Huddersfield on 3 May 1997.
His mother and aunt featured on the BBC's Crimewatch show on Wednesday.
West Yorkshire Police said they had received calls offering information on possible suspects.
Det Supt Dave Pervin made a direct appeal for Joe's killer to come forward during the Crimewatch programme.
He said: "Following last night's Crimewatch appeal, we have received a number of calls from people providing us with new information.
"We will now look into this information to see where it may take us.
"Obviously for operational reasons I cannot go into more details but I am very pleased that the programme was met with such a positive response."
Mr Pervin said Joe's mother Tracey was "also very pleased and we are all now hopeful that this new information will lead to Joe's killers being brought to justice".
Police have urged anyone with information about Joe's death to contact them or the Crimestoppers charity anonymously.
