A teenage thug faces being locked up after he was convicted of a vicious knife attack which left a man with serious injuries.

Johnny Brazil was found guilty of unlawfully wounding Jack Lupson and one offence of common assault.

The 19-year-old, of Barrow Green, Teynham, was cleared of the more serious charge of wounding with intent, a second charge of common assault and making a threat with a knife.

Maidstone Crown Court heard Brazil pulled out a knife and stabbed Mr Lupson after he had earlier assaulted him outside a shop in Faversham.

The victim had to be airlifted to a London hospital for surgery to a wound to his abdomen.

Mr Lupson and his friend Martin Brewer had been out shooting on August 1 last year and then went to Davington Stores in Priory Row.

After Mr Lupson pulled up outside in his VW Golf, a Toyota stopped behind them.

Mr Brewer went to the car to talk to some friends in it.

Brazil, who he did not know, was sitting in the front passenger seat and asked what he was staring at.

Mr Brewer, 28, walked off to the shop. Brazil followed and punched him hard in the face, leaving his nose and mouth bleeding, said prosecutor Bridget Todd.

Mr Lupson tried to calm things down but was also punched by Brazil.

Neither Mr Brewer or Mr Lupson retaliated, said Miss Todd.

Brazil, then 18, returned to the Toyota and it drove off.

Mr Lupson took his friend home and then went to Barnes Close to “sort it out”.

He went towards a house shouting: “Get him out here now.”

He saw Brazil and attempted to punch him. The teenager pulled out the knife and stabbed him.

A resident saw Brazil running down the road with a large knife in his hand shouting: “Do you want it?”

Brazil - known as Baby John - ran to a car, got in and it sped off. He dumped the knife in a hedge in Lower Road, Teynham.

It was recovered by police. Officers went to his home in Teynham and found him hiding behind a sofa.

Miss Todd said Brazil stabbed Mr Lupson “in a cold and calculating, deliberate act”.

The victim was taken by air ambulance to King’s College Hospital in London with a suspected punctured colon. He was detained for six days.

Brazil, who denied the charges, will return to court on Friday. He was remanded in custody.
