@thedisasterautist The Met are appealing for victims to contact them.
Even with the best investigative journalism, victim accounts, those journalists aren't 'official investigators' in the scope of the law; police need complainants: victims to come to them.
I have known police make arrests when there have been no complainants, but via corroborated witness accounts and our CCTV proved an offence, but I'm reasonably sure collated 3rd party evidence (media) cannot instigate a police response.
