A teenager, who cannot be named for legal reasons, has now been sentenced to six years and eight months after pleading guilty to section 18 wounding and causing actual bodily harm yesterday (November 4).
He was also served with an indefinite restraining order to prevent him from contacting the victims.
Det Insp Andy Horne, of Lancashire Police, said: "Officers located the first victim collapsed on the road bleeding heavily and administered life-saving first aid until the paramedics arrived.
"He spent two weeks in hospital receiving treatment for his injuries, before being readmitted following complications, which required further surgery.
"After a methodical investigation, and due to the bravery of all witnesses involved, we were able identify the defendant and bring the case to court.
"We hope that today’s sentence will give out a clear message that if you commit serious crimes like these you will face the consequences."
