A teenager has been jailed for three years for stabbing a man in Chesham in an unprovoked attack.

Yasin Haji-Osman, 18, of Welbeck Road, South Harrow, approached the victim, a 49-year-old man who was walking in the High Street after a night out in the town centre at 11.30pm on March 13, and became involved in a fight during which he stabbed the victim.

Police say the victim, who did not know Haji-Osman, suffered a single stab wound to his lower abdomen.

Haji-Osman was arrested on a train bound for London on the same night and charged the following day.

He pleaded guilty on April 17 to one count of attempted Section 18 GBH and a count of possession of an offensive weapon in a public place and was jailed last Thursday, police confirmed today.

Investigating officer detective constable Sarah Lewis, of Aylesbury Force CID, said: “The victim was stabbed in an unprovoked attack by Haji-Osman, who he didn't know, while walking home from a night out.

“This kind of behaviour is unacceptable and Thames Valley Police will continue to work to ensure offenders of violent crimes such as Haji-Osman are identified and are brought to the courts to face justice.”
