Two teenagers who chased their victim through the streets before stabbing him six times with a machete have been jailed for 21 years.

CCTV footage showed the two attackers at Westcliff station in Essex on Monday October 22 last year, after they had chased their victim to the platform.

They were then joined by a third man, Abdi Hashi, 19, and continued to corner the victim on a waiting train, before stabbing him six times in the neck, chest and leg.

The victim, who was in his late teens, was saved by an off-duty nurse and a member of St Johns Ambulance service, who had luckily been on board at the time.

The attackers were filmed chasing their victim through the streets before they arrived at the station

Hashi was seen entering the station after dropping his bike at the entrance before walking in

He was then rushed to a London hospital where he underwent surgery, spending the next two weeks in hospital.

A 17-year-old, who cannot be named for legal reasons, was also seen with Hashi carrying a machete, both were found guilty of causing Grievous Bodily Harm.

A third teenager was also seen in the video in a grey coat – but was not identified.

Basildon Crown Court heard that the victim had been chased from a nearby takeaway and footage showed the 17-year-old running after the victim.

Abdi Hashi (pictured above), 19, was jailed for 13 years, and the 17-year-old also involved in the attack was jailed for eight years

This is while Hashi was seen at the station throwing his bike to one side before running in. After the train had travelled one stop all three fled.

A week later both Hashi and the 17-year-old were tracked down. Hashi at his home in Harrow and the 17-year-old at his home in Southend, the Essex Echo reported.

On Friday Hashi received 13 years in prison and the 17-year-old received eight and a half years.

Det Con Insp Sam Blackburn of the British Transport Police said: 'It's very fortunate that this attack did not result in a death; and it's a testament to the professionalism and skill of the attending medics that the young victim will live another day.

'The victim and his attackers were known to each other and the incident itself is believed to have been gang related. Nevertheless, this was a vicious assault which is thankfully something we rarely experience on the rail network.

'Both attackers will now serve a substantial period of their adult lives in jail, and I hope the severity of their sentences will force them to question their violent behaviour.'
