Three suspects are being sought by police after a woman was punched and kicked during a brawl between transgender activists and radical feminists.

The 60-year-old victim was punched in the face, knocked to the ground and kicked after one of the suspects tried to grab her camera as she was filming at a gender recognition talk, the Metropolitan police said.

Officers are trying to trace a man and two others, who are believed to be transgender, over the attack at around 9.30pm on Wednesday 13 September at Speakers’ Corner in Hyde Park.

Video posted on social media appears to show the confrontation between two groups of people, some holding placards railing against misogyny and featuring the word TERFs, short for trans-exclusionary radical feminists.

Police said the first suspect is a man described as white, around 6ft and with brown hair in a pony tail.

They give no gender for the two others, with one said to be white, around 5ft 8in, of slim build and with short blonde hair, wearing a black, grey and white hooded camouflage jacket and multi-coloured leggings.

The third suspect is described as white, around 5ft 7in, of slim build and with brown chin-length hair with blond tips, wearing a black, grey and white camouflage hat, a black pullover top and black jeans.

The victim suffered bruising but did not need medical treatment.

A 26-year-old man who came forward on 6 October was questioned under caution but not arrested, the Met said.
