Mohammed Dirir, 27, was the victim of the vile racist abuse and said that he resisted the urge to fight the men
Mr Dirir asked them to repeat the monkey gestures, so he could capture it on video.
Other commuters could be heard sympathising with him as he was repeatedly abused by the gang of six.
Despite being challenged several times, the group were unapologetic and laughed and joked about the abuse.
Mr Dirir, from the Netherlands originally, has lived in London for eight years and is the founder of his own start-up buisness.
He told Mail Online: 'I was on the train, minding my own business. I saw a group of white men getting on and they saw me and started doing these monkey noises and these monkey movements.
'I tried to ignore it as much as possible but one of the guys gave me a thumbs up and then I realised he wanted me to know I was being targeted.
'So I asked him, ''are you good mate?''. Then he said to his friend that I was dumb and I didn't get it.
'Fast forward, I tried to get some video footage and as you saw, they were really racist. I could've fought them but then again, everybody would say I was just responding to hate with hate and adding more fuel to the fire.
'Being the man I am, I was raised to show love rather than hate and I had to set an example. You saw what happened.
'We need to stop the hatred around the world man. All this racism that's going on, it's nonsense. We're all the same.
'Ignorant people like that need to be guided and I pray to God that he guides them.'
Swinging around and making monkey noises?
hmm
