Detective Constable Luke Flood, from the Central South Command Unit which polices Lambeth, said: “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.
“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.”
Anyone who can assist police is asked to contact 101 and quote CAD117/14MAR. Alternatively, information can be provided to Crimestoppers, anonymously, on 0800 555 111.
