A TEENAGE thug who attacked an air ambulance pilot on an emergency call in Sevenoaks has been locked up for three years after another vicious assault.

Joshua Young, of no fixed address, was on bail for the air ambulance offence when he seriously wounded victim Matthew Smith with a broken bottle during a party in Riverhead.

The incident happened on June 12, the night of England's 1-1 draw with USA in the World Cup.

Maidstone Crown Court was told Young lashed out at the party in Bullfinch Close, after hostility was directed towards him over the air ambulance attack.

Prosecutor Alex Wilson said more than 60 people were packed inside the small terraced house.

He said Young was involved in a scuffle with another teen when Mr Smith, now 17, intervened.

Young faced up to Mr Smith with an empty beer bottle in his hand, and when Mr Smith tried to scare him away, Young put down the bottle and punched him.

Mr Wilson said Smith punched him back, and continued: "Young made a sudden stabbing motion towards Matthew Smith's arm. He felt pins and needles all over his body.

"He was losing blood from an open wound to his left wrist. He was punched and kicked by a number of people."

One witness, he said, described Young climbing on top of Mr Smith and hitting him repeatedly with the broken bottle.

Mr Smith was taken to Kent and Sussex Hospital, then to the Queen Victoria Hospital in East Grinstead with a towel round his wrist to stem the bleeding.

He suffered nerve and tendon damage and requires ongoing physiotherapy.

Young admitted wounding with intent. He had earlier been sentenced to four months detention on June 14 for the assault on the air ambulance pilot – who had flown a paramedic to treat a scalded baby – on May 23 at the Vine sports ground in Sevenoaks.

His lawyer, Caroline English, described the earlier incident as "infamous" and said: "It caused a great deal of hostility towards him. He didn't handle it well."

She said her client was intoxicated by drink and cocaine.

Judge Philip St John-Stevens said Young had a worrying list of convictions.

He told Young: "Whatever the situation, you chose to pick up a bottle and use it as a weapon. With the use of broken glass there is a high risk of serious injury."

The new youth custody sentence will run from September 26, when Young has completed the four-month term.
