Police are looking for a man who exposed himself to a woman during the vigil for Sarah Everard in south London.
It happened at around 8pm on Saturday 13 March as hundreds of people were gathered on Clapham Common to remember Ms Everard who was found dead after she went missing.
Detectives have released an e-fit of the man they claim exposed himself to the victim as she walked on the southside of the common near the junction with Windmill Drive.
He is described as white, around 50 years old, 5ft 6in tall, with grey hair. He was seen wearing a bright red waistcoat or vest over a shirt and light-coloured trousers.
DC Luke Flood of Lambeth Police is urging people who attended protests that day to check any photos or footage they may have taken.
He also said he "cannot discount that there may have been other incidents of this nature" on the common that evening.
"I am appealing to anyone who was in the area or who can help identify this man involved to contact police. Clapham Common was extremely busy on that Saturday evening with people attending a vigil," he said.
"An incident of indecent exposure can be an extremely distressing offence for those who witness it and it is one police take very seriously.
"Officers have spoken to the victim in this case to offer her support and ensure she is kept updated with the progress of the investigation."
Police were heavily criticised for their handling of the protest, which took place despite campaign group Reclaim These Streets losing a High Court battle to carry it out safely and within coronavirus rules.
Officers were seen clashing with female protesters, including one who was pictured face down on the ground with her hands behind her back.
Critics later called for Met Police Commissioner Cressida Dick to resign.
Ms Everard, 33, disappeared as she walked home from Clapham to Brixton on 3 March.
Her body was found in Kent a week later.
Wayne Couzens, 48, a serving Met Police officer, has been charged with her kidnap and murder.
