As a Wealdstone man begins an eight-year jail term for stabbing his victim in the head, details have emerged of his part in a chain of events that led to the murder of a foreign leader's son.

Warsame Guiled, 25, of no fixed address, had a fight with a 23 year-old man last December last year, which ended with Guiled stabbing the victim in the head outside Cashino amusements arcade in High Street, Wealdstone. It caused a three inch cut above his right ear.

Guiled, formally of Eaton Close, Stanmore, was sentenced on Friday at Harrow Crown Court to eight years' imprisonment for grievous bodily harm with intent and concurrently to one year in jail for possession of a bladed article in a public place.

Detective Constable Amin Kohzadbayat of Harrow CID, described the incident as "a nasty attack on a member of the public" and added: "I hope the sentence will serve as a warning to those intent on carrying knives on the streets of Harrow."

It can now be revealed Guiled was caught up in a spate of violence in Wealdstone in 2009 - an escalation of a rivalry between a largely Somali group and a largely Afghan group - that claimed the life of Hassan Kul Hawadleh, the 19-year-old son of a former Somali Prime Minister, of West Hendon, who was stabbed to death on the forecourt of the Total Garage in High Road, Harrow Weald.

Guiled had broken the nose of Mr Hawadleh's eventual killer Abdul Khan, then 19, of Enderley Road, Wealdstone, while winning a one-on-one street fight in Wealdstone on February 16 2009.

Three days later Khan rounded up associates and sought out to settle the score. They cornered Guiled in the William Hill betting shop in High Street, Wealdstone, and beat him with their fists and a chain. Less than an hour later Khan spotted Guiled's cousin Abdiwahab Guiled and two friends, including Mr Hawadleh, at the Harrow Weald Service Station and Khan and his associates charged the trio.

Mr Hawadleh was fatally stabbed coming to the aid of Abdiwahab Guiled, who was stabbed in the buttocks, severing a nerve.

Onochie Madekwe, then 34, Michael Boyde, then 28, and Andrew Spence, then 22, were cleared of murdering Mr Hawadleh but received short prison sentences for violent disorder relating to attack on Guiled.

Khan was convicted of murdering Mr Hawadleh by a jury in June 2010 at a separate trial, admitted violent disorder and causing grievous bodily harm, and was cleared of the attempted murder of Abdiwahab Guiled.

Khan was jailed for life with a minimum tariff of 22 years.

Former Harrow College student Mr Hawadleh had arrived in the UK in 1991 and was in the second year of a surveying degree at East London University. He lived with his mother and siblings in Colindale following the death of his father Mohammed Hawadleh, a former prime minister of Somalia.
