A man who tweeted last weekend about an alleged incident of racist bullying by Transport for London and the Metropolitan police has lodged a formal complaint with those agencies.
The man's lawyers confirmed in a statement to BuzzFeed and on Twitter that a formal complaint was lodged today with the Met and TfL.
His tweets about the incident went viral last weekend, receiving thousands of retweets and sparking a discussion on Twitter about racism in Britain.
The man, whose name has not been confirmed, although he goes by Psymon L'Amour on his Tumblr page, claimed to have intervened in a disagreement between a TfL official and three young girls on a bus in the London borough of Redbridge.
He claimed that the TfL official then phoned the police to say he was being threatened.
He then tweeted that "2-3 minutes later, 3 police cars, 1 bike, 8 officers & 4 revenue protection officers surrounded me & tried [to] bully me".
The man claims to have video evidence of racial abuse by one of the Met officers. He has not yet shared the videos, but told BuzzFeed that he plans to do so in a few days' time.
A few days later, he claimed to have been unlawfully detained.
He then said the police had no grounds to charge or arrest him.
In one tweet, the man shared a photo of an officer, who, he claimed, "stated my people (?) deserve such treatment & it isn't my business to question them".
He alleged that police harassment continued online and at his family home.
The man expressed frustration and thanked the support he received from friends, family, and strangers online.
He told BuzzFeed that "a lot of police officers misuse their powers on a daily basis and people are genuinely scared to speak out about it".
He added that he believes it is "important that more people are aware" of experiences such as his, and went on to say that "judging from some of the responses I've had, this is a very common occurrence."
The Redbridge borough police attempted to reach out to the man via Twitter on Sunday evening, but received no response from him.
The Metropolitan police told BuzzFeed on Wednesday, before the formal complaint was filed, that they were aware of the incident, and that "an investigation is under way".
They said the investigation is "at an early stage" and that they could not comment any further at the moment. They added that the Met encourages anybody who feels they have been mistreated in some way to make a formal complaint.
BuzzFeed reached out to the Met again today, but it does not yet have an official statement regarding the complaint.
Many commenters shared their outrage over the incident the man depicted in his tweets on Twitter.
BuzzFeed will continue to follow this story as it develops.
We are currently awaiting further comment from TfL.
