Shocking footage shows the moment a thug sprays clubbers with a 'noxious substance' in a mass brawl outside a nightclub.

Huseyin Onel, 24, squirted the liquid at the faces of revellers after they tried to stop an attack on man outside the venue in Hackney, east London.

The man, who police have not been able to trace, had been punched and kicked after he approached a group of men who were sitting in cars in Alvington Crescent at 5am on May 5.

Another group leaving the nightclub then tried to stop the attack, but when one of them began filming the scene on his phone, the men turned on him.

As the fight escalated, Onel got a bottle from one of the cars, and then started spraying the noxious liquid in the faces of victims, the Metrpolitan Police said.

The suspects then got into three cars and drove from the scene, shouting homophobic insults at members of the group, and that they 'run Hackney'.

The man who filmed the assault was left with a fractured eye socket and corrosive burns to his eye, the force said, adding that he had made a 'miraculous' recovery.

Seven men were yesterday jailed for a total of nearly 60 years, with Onel sentenced for 17 years for applying a noxious substance causing grievous bodily harm, and three years on extended licence.

He was given nine years each for six counts of casting a noxious substance and three years for violent disorder to run concurrently.

The men were sentenced at Wood Green Crown Court yesterday.

Det Con David Leitner led the investigation. He said: 'Nine violent and dangerous men have been removed from London's streets today and will now spend a lengthy time locked up in prison.

'The level of violence used in this attack, coupled with the speed that this incident escalated, are truly shocking.

'A group of people who were enjoying themselves at the end of a night out were subjected to a sustained and relentless wave of violence including the use of a corrosive substance – because they acted as good Samaritans to help a male being subjected to a vicious assault.

'The original victim who was attacked by the group has never been traced but I hope he, and all those who were set upon by this violent group of individuals, will take some comfort from the fact that this group has been convicted.'
