A mother today condemned young thugs who robbed and beat her teenage son and left him naked in a park.
David Procter, 16, was forced to strip and hand over jewellery and his mobile phone, before being viciously punched and kicked in the head and body.
His three attackers also set two dogs on him and he was bitten on the ear.
The youngster, who suffers from asthma, was left with serious facial injuries, including a broken nose, fractured cheekbone and broken teeth.
A passing motorist draped a blanket around him and took him to Bradford Royal Infirmary for treatment.
Detectives are investigating the "unusual" incident.
David's mother, Julie Procter, said she could not believe what the attackers had done to her son when she saw his injuries in hospital.
She said: "It was bad enough David being beaten up and robbed, but then to take all his clothes and leave him there was beyond belief. All they left him with was a little eye stud."
He had been treated at BRI for chest pains brought on by his asthma and had set off to walk to his father's home in Holme Wood when the attack happened, at around 1am last Sunday (April 20).
David said: "I was at the entrance to Lister Park. I saw a young Asian lad and asked him for directions. He whistled two others over and they offered to take me in a car. I thought something was a bit dodgy and I said I would walk. When I turned to go they started on me."
The teenager said he was forced to hand over his mobile phone and items of jewellery.
He was then made to strip off all his clothes.
But when he tried to hand over a gold chain he had to rip it from his neck to get it free.
"One of them said: I wanted it all together' and they started beating me up," said David. "One lad punched me twice in the face, knocking me to the ground. All three then just started kicking me in the side and the face.
"I was covering my face up. I was frightened and in pain. Then they set the dogs on me. I just wanted it to end and to go home. They didn't say anything while they were beating me. Then they just walked off and left me on the ground."
He added: "They need locking up. If it has happened to me, it will happen to somebody else. One of the nurses told me it happens quite often in that area."
Police took David back to the park so he could identify the place the attack happened. He has also given a statement and had his injuries photographed.
Detective Inspector Gerry O'Shea, of Bradford South CID, said it was a highly unusual type of crime.
"The stealing of the clothes is quite bizarre and using dogs in the crime is unusual in itself.
"It is being actively investigated and we are looking at a number of inquiries, which includes checking CCTV in the park.
"We urge anyone with information to contact the investigating officer, PC Louise Matthews, of Bradford South Police, on 0845 6060606, or Crimestoppers, anonymously, on 0800 555 111."
One of the robbers was aged 16 or 17, slim, 5ft 9ins tall, with short dark hair and spoke with an English/Asian accent. Another was aged about 17 and 5ft 9ins tall. The third suspect was about 18, slightly taller than the others, slim, spoke with an English/Asian accent and wore an orange and black horizontally-striped jumper. He had the two Staffordshire Bull Terrier-type dogs on leads.
Mrs Procter said: "I want to thank the person who took David to hospital. These thugs had beaten him black and blue and left him without a stitch of clothing."
