Nine members of an east London gang have been sentenced to prison for a homophobic attack carried out last year.

Huseyin Onel, 24, and eight other men targeted their first victim in Dalston on 5 May, a bank holiday.

CCTV footage of the attack has been released.

The incident unfolded after a verbal altercation between an unidentified male and Onur Ardic, 27, who was part of the group of nine men.

The unidentified male went to speak to Ardic and was quickly surrounded by the group, who launched an attack, punching and kicking the victim.

A group of people attempted to intervene to stop the attack with one of them – a man in his 20s – filming the assault.

The group then attacked the man, kicking him to the ground and attempting to steal his phone. A number of this victim’s group went to their friend’s aid and a large brawl erupted.

During this, Onel used a bottle to spray a noxious substance in the faces of a number of people.

Other members of the group – Mehmet Tekagac and Onur Ardic – were also involved in the corrosive substance attack on one of the group.

The second victim who tried to film assault suffered a fractured eye socket and another person suffered burns to their tongue.

The gang then got into three cars and drove away from the scene, shouting homophobic slurs.

All nine were sentenced at Wood Green Crown Court on Thursday.

“Shocking” attack

Detective Constable David Leitner, who led the investigation, said: “Seven 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.”
