Police are hunting for three people wanted over an assault at a transgender rights event in Hyde Park - but have refused to give their gender in case they get it wrong.
Maria MacLachlan, 60, was punched in the face and knocked to the ground at Speakers' Corner on September 23 by suspects including one clutching a 'trans misogyny is still misogyny' placard.
The mother-of-two, who describes herself as a 'gender critical feminist', was attacked at a 'gender recognition talk' in central London last month.
Describing the suspects in the attack, a Scotland Yard spokesman told The Telegraph: 'We have to be very careful.
'We are not going to commit ourselves to something because I'm afraid it's not black and white.'
Ms MacLachlan was filming members of the Action for Trans Health (ATH) group who attacked her and took her memory card.
Supporters of the trio accused of attacking Ms MacLachlan later said it was acceptable to punch her because she was with Trans-Exclusionary Radical Feminists who believe you can only be a woman if you were born one.
Scotland Yard has today released images of the suspects they want to trace.
Suspect one is a white man, around 6ft tall, with brown shoulder-length hair worn in a pony tail.
Suspect two is described as white, around 5ft 8inches tall of slim build with short blonde hair and wearing a black, grey and white hooded camouflage jacket and multi-coloured leggings.
Suspect three is described as white, around 5ft 7inches tall of slim build with brown chin-length hair with blonde ends and wearing a black, grey and white camouflage hat, a black pullover top and black jeans.
The altercations came as members of the Action for Trans Health (ATH) clashed with their bitter enemies the Trans-Exclusionary Radical Feminists (TERFs) before a scheduled event to discuss gender issues.
Ms MacLachlan said she was talking to one of the event speakers Miranda Yardley when 'studenty-looking types' turned up and began arguing.
She said the protestors shouted 'when the TERFs attack, we fight back' and she decided to start filming
'Then suddenly someone tried to grab my camera,' she said. 'It was scary. Someone kept trying to get my camera. I think it was a girl, but I couldn't tell because they had a hoodie over their eyes.'
After the attack ATH's Edinburgh branch sent a series of tweets defending the use of violence.
They said: 'Punching terfs is the same as punching Nazis. Fascism must be smashed with the greatest violence to ensure our collective liberation from it'.
'Violence against terfs is always self defence', another tweet read.
Elsewhere on social media ATH supporters say 'TERFS must die' and 'burn in a fire, TERF'.
Before the meeting, one supporter posted: 'Any idea where this is happening? I want to f*** some TERFs up, they are no better than fash [fascists].'
