The Met: Policing London episode six

In south London, 38-year-old Julian Joseph is violently attacked on a bus and is rushed to hospital in a critical condition after repeated kicks to the head. The detectives' priority is to identify the man on the bus CCTV fleeing the scene of the crime. But the suspect makes a fatal error when he tries to return to the bus after the attack, leaving a handprint on the door of the bus that gives the detectives a vital clue. Meanwhile, Julian's mother remains by her son's side in hospital, but nine days after the attack her son dies from his injuries. Now all she can hope is that detectives find the man who attacked her son and bring him to justice.

Our Public Order Command police 250 protests across the capital every year, and this year three of those protests happen during President Donald Trump's first visit to the UK. It's their responsibility to keep the president safe and to facilitate any peaceful protests. The first day involves the woman's march and the launch of the Trump blimp. It goes largely without incident. But on the second day of protest, pro-Trump and anti-Trump supporters come face to face. It isn't long before officers have to intervene, and the police themselves come under attack when disorder breaks out among pro-Trump supporters in Trafalgar Square.

In south London, response officers PC Ben Anawachagul and PC Tom Dicks are on patrol in Croydon city centre when they are called to assist enforcement officers trying to evict a traveller in his caravan from a supermarket car park.
