Here are 14 that happened during the first episode

1. Viewers including Pointless’s Richard Osman were really excited #policecustody was back.

2. A small town near Luton was suffering a spike in teenage violence. The suspect was 19-year-old Dylan McEwan.

He was arrested on suspicion of robbery. He claimed he had been stabbed in the bum with a piece of wood laden with nails.

3. This was the dream team of detectives who wanted to talk to him. Meet Detective Sergeant Emma James and Detective Constable Cathie Layton.
