'Thugs in uniform' council enforcement officers who threatened to 'rip out' man's teeth are unmasked as it's revealed they 'acted like gangsters' for weeks

A pair of council enforcement officers who caused outrage when they were caught on camera making disturbing threats to beat up a member of the public had been 'acting like gangsters for weeks', the Daily Mail can reveal.

The two 'thugs in uniform' can today be named for the first time as Joseph Fernandes, 38, and Umar Siddiq, 30, both of whom have now been sacked by Harrow council over their aggressive conduct.

The pair had attempted to issue a £100 fine to a terrified teenager they accused of spitting then angrily turned on a member of the public who stepped in to support her, saying: 'I'm going to knock you the f*** out and rip your teeth out.'

Today the Mail can reveal the pair had been using intimidatory tactics to coerce members of the public into paying fines for supposed civil offences in the days leading up to the threat that got them fired.

Among a series of incidents they are said to have snapped off one motorist's car key in the ignition to prevent him from driving away while they pressured him - and left a vulnerable elderly woman resident in tears by falsely accusing her of dropping litter before threatening to call the police if she didn't pay £100.

The pair are also alleged to have had an animus against Hindus and Sikhs and to have mercilessly targeted members of both communities around the north-west London borough.

We have further learned that the resident they threatened in the now notorious video had incurred their fury when he intervened to protect a young woman he saw them trying to bully over a trumped up charge of spitting on the pavement.

The confrontation - which later went viral and was captured in footage from a hidden camera  - saw both enforcement officers verbally lash out at a 23-year-old heating and air conditioning engineer, who only wanted to give his first name, Alvin.

The officers told the member of the public - Alvin, 23-year-old heating and air conditioning engineer - that they would 'rip his teeth out' during his run in with the pair

But the furious bust-up on May 18 on a stretch of the Northolt Road, close to South Harrow tube station, was just the latest in a string of incidents in which Fernandes and Siddiq stand accused of adopting bully boy tactics.

Speaking exclusively to the Daily Mail, Alvin said he had turned out of the underground station onto the Northolt Road after finishing work when he saw the pair - who were both wearing hoodies under hi-viz jackets - targeting a woman, who looked to be in her teens.

Seeing her distress, Alvin went to support her, advising her that she did not have to pay a fine for spitting if there was no evidence that it had happened and advising her to keep on walking.

That intervention prompted the angry reaction from the enforcement officers as Fernandes and Siddiq then aggressively turned on him.

In the footage - filmed on a secret camera embedded in his Meta sunglasses - both men, who worked for Kingdom Services Group and had been contracted by Harrow Council, squared up to him.

Explaining the chain of events, Alvin - whose face we have agreed to partially conceal over concerns for his safety - said: 'I'd finished work and was heading home from South Harrow station.

'I started walking towards Wenzel's bakery and I saw the enforcement officer with the long beard tap a young girl on her shoulder and then whisper something in her ear. That was red flag number one.

'He must have asked her to step to the side and follow him because she moved away from a busy bus stop and went to move towards a back street. That was also strange and so that's when I stepped in.

'I intervened and said to the officer 'Excuse me, who do you work for? The council or a private company?'

Siddiq, who lives in a top floor flat with his family. had been working the stretch of Northolt Road since March - but has now been sacked by the council. When asked to give his account of what happened, he said: 'The video online was taken out of context.'

Fernandes is a fitness fanatic and personal trainer who was last listed living at a £900,000 semi-detached home with his aunt

'He didn't say anything, just stared. I repeated myself and again he said nothing and looked right through me. The girl was in her teens and she looked scared so I told her: 'You don't need to say anything or pay anything….just walk on and get on the bus.'.

'She did just that and the officer didn't like it all. We exchanged a few words. He was raging at me, saying 'Why are you butting in? Why are you messing with my money?'

'He started swearing at me asking me 'why are you f***ing with my business?'

'We started to part ways and I said 'you're such a p***y for doing what you do. You shouldn't be doing things like that'.

'That's when he became more aggressive and came towards me with his colleague. I had my Meta…
