A youth who robbed a foreign student and threatened to stab a man has been sent to a young offenders' institution for two years.

The 17-year-old, who cannot be named for legal reasons, admitted two counts of robbery and one of attempted robbery.

The first victim was a Turkish student on July 22 last year in Southbourne, Bournemouth Crown Court heard. The defendant was joined by another youth carrying a knife and the terrified student handed over his wallet and phone.

When the juvenile was arrested six days later the phone and a 20-inch bladed knife were found on him.

While on bail for this offence he challenged two men walking along Bournemouth seafront on September 24, telling one: "Give me your phone or I'll stab you."

His co-accused, David Gater, 18, from St Swithuns Road, Bournemouth, and Martin Peters, 20, of no fixed address, admitted attempted robbery. A 17-year-old girl, who was with them, admitted handling a stolen mobile phone.

Defending the juvenile, Richard Ferry-Swainson said he and his co-accused in the Southbourne robbery had shared 24 cans of lager before the attack.

Judge Samuel Wiggs imposed a two-year detention and training order on the male juvenile. Peters received a suspended two-year sentence and was ordered to carry out 100 hours unpaid work.

Gater was given a 12-month suspended sentence and a six-month curfew while the female juvenile was made the subject of a 12-month community rehabilitation order.
