A young woman is violently mugged for her phone and handbag by two moped thieves, and is rushed to hospital in a critical condition. The investigation is handed to DI Steve Brownlee who runs a specialist team of detectives tracking down the capital’s most violent and prolific moped criminals. On CCTV they identify two men using the victim's stolen bank card 15 minutes after the attack, but tracking the men down proves more difficult for the detectives.

Meanwhile, PCs Andy Reeder and Allan Baker-Perkins are part of a response team that patrol London’s hotspots for moped crime. Determined to reduce the number of crime,s the unit use a controversial technique called tactical contact. They pursue a man on a moped who they believe has stolen some handbags, and when the rider refuses to stop, the team chase him, knock him off his bike and wrestle him to the ground.

Knife crime is a major concern for the Met’s senior command team overseeing the 2018 Notting Hill carnival. For the first time in the carnival’s 50-year history, the Met authorise a section 60 for the entire duration of the event, giving them the powers to stop and search anyone for weapons or drugs without reasonable grounds. In the previous year there were four serious stabbings at the carnival, and two years before there were 12 stabbings. With huge crowds of half a million wanting to enjoy the carnival, it’s a tricky balancing act for gold commander Dave Musker, whose job is to keep the huge carnival crowds safe. Show less
