One of the two men who carried out a brutal knife attack on a 16-year-old boy in a row over a missing dog can be seen smirking in his mugshot as he was jailed.

Braydon Hall, 20, and Jake Grainger, 18, attacked the teenager after he lost a Rottweiler dog he had been asked to look after by a group of associates.

He was left with life-threatening injuries after being repeatedly stabbed in the neck and chest following an argument in a park.

The blade passed through his throat and out the other side, and he was also stabbed in the stomach, back and bum.

He was left to "bleed" by his cowardly attackers who fled the scene in Rye Park, Hoddesdon, Hertfordshire on October 22 last year.

Jake Grainger admitted grievous bodily harm

At St Albans Crown Court on Thursday, Hall was jailed for 11 years after admitting grievous bodily harm and possession of an offensive weapon.

Grainger was sentenced to six-and-a-half years after pleading guilty to grievous bodily harm.

An indefinite restraining order has also been granted, preventing the pair from contacting the victim.

Braydon Hall admitted carrying out the attack

The horrific attack happened in the morning as the youngster was confronted by the two men.

He was taken to hospital by air ambulance and received life-saving treatment.

Detective Inspector Justine Jenkins, of the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit, said: "This was a shocking and isolated incident between parties who were known to each other.

"Those responsible were quickly identified, arrested and charged.

"Knife crime will not be tolerated in Hertfordshire and we do everything we can to bring those responsible to justice.”

She added: "A young man very nearly lost his life in this incident and was saved by the actions of members of public and health professionals at the scene.

"The victim spent a significant amount of time in hospital being treated for his injuries before being discharged, but he still lives with the trauma of what happened to him."
