A man was caught on camera unleashing a torrent of anti-Semitic abuse at a Jewish family while on the tube.

Police are investigating after footage of the abuse was shared on social media.

The clip shows man reading anti-Jewish passages to two young boys while they were travelling with their family on a Northern Line train on the London Underground.

In the video, two passengers are sat down on the south-bound, Charing Cross-branch train wearing kippot on the crowns of their heads.

A man standing near the door, who is wearing a blue jacket and baseball cap, leans over toward them as he reads aloud from a text in his hand.

He can be heard saying phrases including references to the 'synagogue of Satan' and reading 'I will make them come and worship before your feet'.

The father puts his arm around his son and tries to distract him by talking about other things.

But the other passenger thrusts the book further in front of the boy and continues to talk aloud.

The footage was recorded by a commuter on board a Northern Line train on the underground in London. Two passengers, who appear to be father and son, are sat down wearing kippot as a man standing near the door leans over and reads aloud

Other passengers on the train try to intervene as the man squares up to them.

He says: 'You need to get out of my face or I will smack you right in your nose, man. Back up from me. I'm not no Christian pastor. Back the f*** up from me.'

A woman standing near the confrontation then addresses the man but only snippets of the conversation can be heard.

She says: 'There are children in here. Come on man!'

The man responds by saying: 'Listen, these people are impostors, trying to claim our heritage.

'Do you care about your people?'

She calmly holds out a hand as if to pacify the man and says: 'I respect your opinion...'

But the man cuts her off and says: 'No, it's not my opinion. It's God's words. It's God's words.'

The pair continue to debate while the father-and-son duo begin their own conversation in the opposite direction.

The tannoy sounds as the carriage approaches another stop and the video ends shortly after.

Journalist Chris Atkins, 43, who took the video, said: 'I've lived in London for 20 years and you're used to people ranting on the Tube - it was only after a minute I realised, "hang on this is really, really antisemitic".

'It was the children that really got me and everyone else, he was just screaming at these children. It was horrific in every sense.

'He seemed to be a very committed Christian and believed this was the word of God - that it said in the Bible Jews killed Jesus and they are all slave masters.

'It's the kind of stuff you see on Twitter a lot, but to hear someone actually say it unashamedly was shocking.'

Mr Atkins filmed for around two minutes 'on instinct' before moving to swap seats with the young boy next to the man.

Mr Atkins said: 'I was sat between the guy and the family to try and be a bit of a barrier.

'Then another guy came up and started talking to him who was very good, who basically said "what is it in the Bible?" and "tell me where it shows that" just to divert attention away from the family.

'It was horrific but it was also quite heartening to see Londoners of all creeds and colours taking him to task.'

Mr Atkins said the family got off the train a few stops later at Leicester Square and the father of the two boys gave him consent to share the video on Twitter.

Mr Atkins said he has spoken to the police and given them information, and said he is willing to give a witness statement if needed.

The video was posted on to Twitter earlier today alongside the caption: 'Around noon I witnessed appalling anti Semitic abuse towards this Jewish Family on the northern line.

'Fair play to other passengers who stood up to him. If you recognise the guy please report to ⁦@metpoliceuk.'

Other social media users were quick to praise both the Jewish family and the intervention by fellow passengers who came to their defence.

British Transport Police said that they had been made aware of the abuse and that their enquiries are still ongoing.

In a statement the British Transport Police said: 'We are aware of a video circulating on Twitter which shows passengers being harassed and being targeted with anti-Semitic abuse on a Northern Line train.

'Enquiries are being made in relation to this footage.

'Anyone who witnessed what happened, or who has any information, is asked to contact BTP by sending a text to 61016 or by calling 0800 40 50 40 quoting reference 357 of 22/11.'
