The witness said the man on the ground who was being attacked was the one who initiated the fight.

'He was bleeding from his lip because he suffered a lot of punches. And he deserved it too,' the witness said.

He explained the altercation began with insults between the three Arabic men and the African man.

'He (the African man) said ''Go back to where you came from'' and ''All immigrants are a problem to this country and you bring all the crime here'',' the witness said.

The witness (pictured) who was not identified, said the African man, who was left slumped on the floor after being attacked by three other men, was the one who started the fight

After this, the insults turned to terrorism.

The witness said the African man told the three other men that all Arabic people were part of ISIS, and that's when the physical fight began.

He said: 'They just wanted to beat she s*** out of him and they did.'

Other passengers sought help from transit guards when the train pulled into Tottenham station.

One man was seen getting off the train and yelling 'Look here, they're fighting on the train. There's one down on the ground now. They seem to be affected by alcohol.'

Transit guards are then seen rushing into the carriage.

According to 7 News police and transit guards spoke to the four men but none of them wanted to press charges or take the incident further, with each group blaming each other for the violence.

The witness to the incident said he thinks public transport needs more security.
