A detective investigating the case of Jack Woodley said the 10 teenagers locked up for his murder "worked together" to create an opportunity where he had "no chance".
The youths, aged between 15 and 18, who cannot be named for legal reasons, were found guilty of murdering Jack in a group attack after attending the Houghton Feast in Houghton-le-Spring on October 16 last year. Newcastle Crown Court heard how the gang were said to be "looking for trouble" before they launched a joint attack on 18-year-old.
The court heard how Jack, who attended the fair with his girlfriend, was attacked and stabbed twice. He was stabbed once to the hip and a second fatal injury to his back, while he was near the Britannia Inn pub on Newbottle Street. Jack was rushed to hospital but tragically died the next day.
