A Hastings man has been sentenced to four and a half years in a young offender institution.
Conor Featherbe, 19, of Ravine Close in Hastings, was sentenced to 54 months custody.
Featherbe appeared at Lewes Crown Court on Friday 7 April after pleading guilty to attempted robbery.
He was also sentenced to 24 months for causing grievous bodily harm.
Additionally, Featherbe received six months for possessing a knife in public.
All the three sentences will run concurrently.
The incident occurred in St Marys Terrace Hastings on the 14 September last year.
The 18-year old victim and his three friends stopped halfway down the street after they had been playing football on West Hill.
They were approached by two young men who demanded their possessions.
The four lads refused to hand them over and a fight started.
During the struggle the victim was stabbed in the leg and torso causing minor injuries that required hospital treatment.
One of the offenders was identified as Featherbe, and he was arrested soon afterwards.
The other one remains unknown so far.
Detective Constable Julian Stokes said;
“This sentencing sends out a clear message out to anyone in the area who takes a knife out and intends to use it for a criminal purpose.
“They can expect to be traced and to face justice.”
