A teenager is starting a lengthy jail sentence after a row over a faulty motorbike ended with a boy being stabbed.

Brothers Monsur Ali and Dilwar Hussain got caught up in a fight in Northfleet after "taking matters into their own hands". It resulted in a 17-year-old being airlifted to hospital with a stab wound.

Eighteen-year-old Monsur Ali has now been sentenced to nine years and nine months in jail after admitting grievous bodily harm with intent and possession of a knife in a public place.

His brother, Dilwar Hussain, 25, was handed a 12-month sentence, suspended for two years, after admitting affray.

The brothers, both of Nelson Road, Northfleet, were sentenced at Woolwich Crown Court yesterday.

The court heard how, at 5pm on Sunday, July 4, police were called to Haynes Road, Northfleet, following reports of a disturbance.

They found a 17-year-old boy with a knife wound who was airlifted to hospital.

Around an hour later, Ali and Hussain were stopped in a blue Vauxhall Astra in Old Road West, Gravesend. The vehicle matched the description of a car seen speeding away from the earlier incident.

The arresting officers found Hussain had traces of blood on his face while Ali had a cut to his hand.

An investigation by detectives from the Kent and Essex Serious Crime Directorate identified that, prior to the incident, three people had visited the brothers' home address.

They were heard shouting and banging on the door demanding the return of money paid to Ali for a motorbike they said was faulty. Ali did not answer and, after the group left, he went to look for them accompanied by his brother.

The pair tracked them down and, during the subsequent altercation, Ali stabbed the victim.

Detective Inspector Ross Gurden, of the Kent and Essex Serious Crime Directorate, said: "This was a shocking incident which took place in daylight hours and caused considerable concern to residents who witnessed it.

"Rather than call Kent Police following the dispute over the bike, Ali and Hussain decided to take the matter into their own hands. Their reckless actions led to a serious injury for their victim and Ali is now facing a lengthy prison sentence."
