A CHILLING reconstruction of a mystery knife attack on a Bingley man will be screened tonight by BBC's Crimewatch programme.

Philip Hey, of Wagon Lane, was the victim of a random and savage attack on December 15, 2012, when a well-spoken stranger plunged a long blade though his neck, missing his jugular vein by millimetres.

Family man Mr Hey, 53, only survived due to his own life-saving skills and stemmed the bleeding himself until paramedics arrived.

The dramatic incident will be shown in an episode due to screened at 9pm on BBC1 and police will renew appeals for information about the shocking and unprovoked offence.

The stabbing took place at about 10.35pm after the Mr Hey opened his door to the smartly-dressed suspect who claimed his brother had been messing about with a torch and he had come to apologise for any disturbance.

Speaking to the Telegraph & Argus soon after the nightmare attack, Mr Hey said: "He took a step back as if he didn't really want to be there then said in very polite BBC-type voice: 'I'm terribly sorry, I've come to apologise for my little brother.

"He's 12-years-old and he's been annoying you with a laser torch'."

Mr Hey said his immediate thought was the lad had been sent to apologise by parents who may have been at neighbouring Bingley rugby club which was hosting a Christmas party.

"He was wearing nice, clean clothes, a smart diamond patterned jumper with a shirt collar, although the sort of clothes more like a middle-aged man might wear to a do at the golf club, not what lads wear, " said Mr Hey, whose two sons are in their early twenties.

"I had no reason to fear him at all, he was polite, well-spoken and came across as well-educated from a good, possibly upper-class background. He didn't have a regional accent.

"He was like a nervous public-schoolboy who lives at home with his parents."

The attacker asked if he might borrow a torch to look for a knife which his little brother might have dropped in the garden.

Good Samaritan Mr Hey briefly invited the well-mannered young man into his house and lent him a torch to carry out his search.

But then when he re-opened the door a few minutes later, the youth attacked with a knife, striking a single blow and then making off with the weapon.

Officers have since published a Efit of the attacker who is described as white, around 20 years old, six foot tall, of thin to medium build and wearing a distinctive, patterned woollen jumper.

He is described as having dark wavy hair, thick bushy eyebrows and was clean shaven.

A Crimestoppers reward of £2,000 is available for any information which may lead to the identification and conviction of a suspect in the case.

Detective Chief Inspector Elizabeth Belton of the Homicide and Major Enquiry Team, said: "We continue to investigate and appeal for witnesses to what was a shocking and seemingly motiveless attack to a man on his own doorstep.

"I hope the reconstruction due to be screened on Crimewatch may help jog the memory of someone who perhaps saw the suspect that night or who may have information which could assist us.

"We have issued an Efit of the attacker and I would ask anyone who recognises the man pictured or can assist our enquiries to call 101 or Crimestoppers on 0800 555 111."

"Even the smallest missing detail could be vital in helping us locate the person responsible and take a dangerous individual off our streets."
