Michelle Ackerley is in Manchester, where she looks back at the events of May 22 - when the city was targeted in the UK's worst terror attack in over a decade. The programme investigates the ongoing training that emergency teams undergo in order to prepare for when the worst happens. And viewers are asked to help catch the man who brutally attacked a pensioner in her own home.

This edition comes from Greater Manchester Fire and Rescue's training facility in Bury, where the team gets hands-on with the Mounted Unit and meets the horses who help police in a variety of ways. And detectives appeal for help to catch the people responsible for a terrifying arson attack.
