A feud between rival Turkish heroin drugs gangs which culminated in a man being shot dead during an alleged attempted prison van escape was caused by a slap in a north London snooker club, it is said.

The escalation caused by the brawl on January 24, 2009 inside the Manor Club in Finsbury Park has led to more than 30 violent incidents across London and southern Turkey, including several murders.

Yesterday, Izzet Eren, 32 and 29-year-old Erwin Amoah Gyamfi, who were on their way to Wood Green Crown Court for sentencing on charges relating to an attempted gangland hit, when a bid was allegedly made to free them from a prison van.

Yesterday's escape attempt is the latest act of violence in connection with a gangland feud between the Tottenham Boys and Hackney Bombers since a row in a snooker hall in north London in January 2009

Police, working on intelligence, were on the scene at the time.

One man was shot dead. The Independent Police Complaints Commission (IPCC), which is investigating the fatal incident, said the person killed was a 28-year-old British man from Tottenham, north London.

Eren and Amoah Gyamfi are both senior members of the Tottenham Boys, also known as the Tottenham Turks. They were on their way to court yesterday for their role in the attempted gangland assassination of members of the rival Hackney Bombers, also known as the Hackney Bombacilar.

Members of both gangs hail from southern Turkey and are heavily involved in the importation of heroin.

According to The Times, more than 10 murders in London have been linked to the feud which began after Kemel Armagan, a senior member of the Hackney Bombers was assaulted inside the club controlled by the Tottenham Boys.

Armagan vowed revenge for the assault and in March 2009 innocent shopkeeper Ahmet Paytak, 50, was gunned down inside the Euro Food and Wines store in Hornsey Road. The killer, Ricardo Dwyer had been hired by the Hackney Bombers for the murder, but shot the wrong target. Mr Paytak had no involvement whatsoever with the Tottenham Boys.

Dyer was jailed 32 years in December 2013 for his role in the murder.

Izzet Eren was shot and injured in Tottenham on September 28, 2009.

Just a few days later, on October 2, 2009, Eren's friend and fellow Tottenham Boy Oktay Erbrasli was murdered as he drove through Tottenham. He was gunned down near the Great Cambridge Road when a man on a high-powered motorcycle pulled up beside his car and opened fire.

The 23-year-old gangster was in the car with his girlfriend and young stepson.

Three days later, the Tottenham Boys launched a gun attack on a club on the Upper Clapton Road used by members of the rival gang and shot dead Cem Duzgun, 21.

Police said that Mr Duzgun, was not involved in any criminality.

The revenge attack was response to the attempt on Eren's life and the murder of his friend.

A post-mortem found that Mr Duzgun was shot 11 times as he played pool at the Clapton FC club in Hackney on October 5, 2009.

He was it in the head, body, arms and legs.

The attack was arranged by leading Tottenham Boy Yusuf Arslan, who had himself been shot in a gangland attack which pre-dated the feud in 2007, aged just 17.

Arslan lost his spleen at that stage and regularly wore a bullet-proof vest - even boasting to police that he could get them better firearms than their standard semi-automatic Heckler and Koch MP5s.

Arslan was jailed for a minimum of 33 years for the murder.

His accomplices Ndombasi Makusu, Christian Barabutu and Blaize Lunkula were all jailed for a minimum of between 18 and 35 years.

Lunkula gained access to the Turkish social club with the help of an accomplice who held open a pair of secure air lock doors.

People inside became aware something was happening and Mr Duzgun went to investigate the lobby area.

Lunkula opened fire, shooting 11 bullets through the victim's head, body, arms and legs. Ballistics experts later estimated the weapon was less than 30cm from Mr Duzgun's head when it was fired.

Lunkula had travelled to the scene with Makusu and Barabutu, who had been involved in planning and organising the shooting.

Mobile phone analysis found that all the defendants had dumped their phones shortly after the murder and did not use them again. Before the killing they had been in contact with each other frequently.

The phone evidence also pinpointed Lunkula, Makusu and Barabutu as being in the area of the club at the time of the shooting.

The other defendant Arslan remained away from the scene, having been the earlier 'organiser' and present at a 'council of war' when the revenge attack was planned.

The Mac 11 machine gun used was not recovered but ballistics experts were able to prove it had been used in two other shootings linked to Hackney Turks premises in 2009.

On February 1, 2012, the Tottenham Boys murdered Ali Armagan outside Turnpike Lane tube station.

The 32-year-old gangster had been spotted driving in the area by members of the Tottenham Boys who informed their bosses, who sent out two assassins.

Armagan was shot half a dozen times and managed to stagger from his distinctive car into a nearby barbers shop where he died.

The Metropolitan Police believe that shooting was carried out by Kemal Eren, who was related to Izzet Eren of the Tottenham Boys.

Kemel Eren, who is known by the nickname 'No Fingers' fled the UK to avoid arrest, but was shot and paralysed in Elbistan, Turkey shortly afterwards.

Then on the evening of December 30, 2012 Inan Eren was shot and wounded. He was left with a permanent limp.

When Mr Eren survived the attack, the target shifted to his cousin Zafer Eren, another leading member of the Tottenham Boys.

The Hackney Bombers outsourced the hit to Jamie Marsh-Smith, who was taken to the scene by his getaway driver Samuel Zerei.

Marsh-Smith put on a Guy Fawkes-style mask and shot Zafer in the back as he walked through the security gates to his home at Fontaine Court off Southgate High Street on April 18, 2013.

Marsh-Smith fired seven shots, three of which hit Eren in the back.

He then escaped in the back of a burgundy Peugeot 308 driven by Zerei.

Four days after that attack, Marsh-Smith shot Zerei in Markfield Park, Tottenham because he feared he would 'blabber'.

Marsh-Smith, of Ennerdale House, Green Lanes, Manor House, north London, was convicted of murder and two counts of attempted murder. He was jailed for life with a minimum of 38 years.

Zerei, of Hathersage Court, Newington Green, north London, was found guilty of murder and sentenced to life imprisonment with a minimum term of 28 years.

Marsh-Smith's half brother, Wayne McNeish, 32, of West End Lane, West Hampstead, was jailed for four-and-a-half years in July for perverting the course of justice by helping Marsh-Smith to flee the country after the shootings.

Yesterday, Erwin Amoah Gyamfi, 29 and Izzet Eren, 32, appeared at Wood Green Crown Court in connection with a feud related hit.

The pair were arrested on October 13 when the Metropolitan Police's Organised Crime Command stopped a motorbike in Stamford Hill.

Amoah Gyamfi and Eren were arrested at the scene.

Police recovered a Scorpion machine pistol, with a full magazine, and a Tokarev 9mm pistol with six founds. Both men were on a stolen motorbike.

Amoah Gyamfi and Eren were both jailed for 14 years.

Four men, aged between 19 and 32, were arrested at the scene. They were allegedly trying to free Eren and Amoyaw-Gyamfi from a prison van taking them to the court.

The Metropolitan Police confirmed they recovered a firearm from the scene.

They are being questioned on suspicion of conspiracy to facilitate the escape of an individual from lawful custody.

Two other men, aged, 29 and 32, were arrested at a different location. They have been released on police bail.

A spokesman for the IPCC said: 'The Independent Police Complaints Commission is continuing its investigation into yesterday's fatal shooting of a man during a police operation in Wood Green, North London.

'Today investigators have undertaken house to house inquiries in the area of Bracknell Close, Wood Green, and they have supervised further evidential searches of the area where the incident occurred.

'A black Audi car, which was the focus of the police operation, has been removed from the scene for further forensic testing.

'The person who died at the scene was a 28 year-old British male of mixed black and white heritage who lived in the Tottenham area. His family have been informed.'
