This is the moment two men attack a police officer as he and his colleague try to pin down a suspect on the floor of a McDonald's.

Shocking video footage shows two officers restraining a man as they try to arrest him at the fast food restaurant in Hackney, east London at 10.40pm last night.

Surrounded by people screaming, shouting and filming the incident on their phones, the clip shows one of the officers raising a police radio above the suspect's head.

As they do so, one person is heard saying 'They're going to kill him' before an onlooker launches himself at the officer, kicking him twice.

The scene then descends into further chaos as the two policemen continue to struggle with the suspect on the floor and the 'hostile' by-standers crowd in on them.

One of the officers is kicked by the same man again and the PC shouts 'get the f*** off me' repeatedly before pointing a taser at another man who approaches him.

Police confirmed the man on the floor was arrested and detained.

One of the suspects seen attacking the police officer was arrested and taken to a north London police station. The other is still at large.

A Met Police spokesman said one of the officers was treated for an ankle injury and the other for cuts to his face. Neither have called in sick and are already back at work.

The Met told MailOnline the taser was 'deployed but not discharged', which means it was switched on but not fired.

The mobile phone footage was posted on Twitter with the caption 'meanwhile.. in hackney #NottingHillCarnival' in the early hours of this morning.

The force appealed for witnesses who knew the other suspect on Twitter today, saying: 'If you witnessed this incident last night please DM.

'If the 'tough man' who feels it's acceptable to kick my colleague in the back, not once but twice when trying to arrest someone, feels any sort of remorse, get in touch too before we track you down. #ProtectTheProtectors'

Dozens of users commented on the video, with some defending the actions of police and others questioning their use of force.

Several branded the youths' behaviour 'disgusting' and said it 'made them feel sick'.

One user posted saying: 'Man pulls out his taser,' with a crying face emoji.

Responding to the comment, the force defended the officers' actions, saying: 'Man got assaulted, not once but twice whilst trying to arrest someone. Think you miss the point here.'

Police had to wade into the debate again when another Twitter user accused them of tasering a man they already had pinned down on the floor.

They wrote: 'I'd also love to know if @MPSHackney can explain why they appear to be tasering someone who is already lying on the floor with two officers on top of them holding them quite easily.'

But the force replied: 'The officers aren't. If you watch it you'll see the officer produces his taser and directs it towards the crowd who assaulted them not once but twice, not the suspect on the floor.'

They added: 'It's down to each officer to justify their own use of force and reasons for it.'

A Metropolitan Police spokesman said: 'Police were called at approximately 22:40hrs on Tuesday, 28 August to McDonalds in Mare Street, Hackney.

'Staff at the restaurant had used the panic alarm and reported that a man was fighting with customers.

'Two response officers attended and detained the man concerned. The officers were then confronted with a hostile crowd some of whom assaulted the officers.

'Both officers were later treated for injuries; one for an ankle injury and the other for cuts to his face. Neither officer has reported sick.

'Colleagues arrived on scene a short time later, a 30-year-old man was arrested for assault on police and taken to a north London police station where he is currently detained. Enquiries continue to try and identify the other suspects involved.'

Acting Borough Commander Steve Johnson of the Central East Command Unit, added: 'Two officers, who were responding to a call to protect the public have been repeatedly assaulted.

'This is an unacceptable, nasty incident, with my officers being kicked while they were on the floor just trying to do their job. I would ask anyone with any information to call us and assist in the investigation.'
