Detectives from the Met's Sapphire team deal with the case of a distressed young woman who has been raped by a stranger on her way home.
London's four major hospital trauma centres treated more than 400 stabbing victims in the first seven months of 2018. The Met is under huge pressure to tackle knife crime and task the Territorial Support Group (TSG) to increase their controversial stop-and-search policy. The TSG target and patrol those boroughs with the biggest spike in violence, but when they try to carry out searches, they face strong and vocal reactions from some members of the community.
In south London, a man wearing a £130,000 Franck Muller watch is robbed at gunpoint in broad daylight. It doesn't take officers long to identify the suspect - a known career criminal who’s already wanted for other offences. But trying to find him is another matter.
