Tonight's 999: What's Your Emergency? to focus on moment coronavirus first struck

Channel 4 show 999: What’s Your Emergency?, which follows police officers as they deal with a wide variety of crimes, will roll back to when the first nationwide lockdown was brought in.

Publicity for tonight’s show, which airs at 9pm, describes the ‘strange new world’ of Covid-19 – and an increase in ‘erratic behaviour’ from members of the public.

It said: “Returning to the moment the coronavirus first hit - with everyone propelled headlong into a strange new world, struggling to keep pace with the dramatic impact on everyday life.

"The crisis has affected every aspect of policing, from the first point of contact in the call handling centre to the rapid adaptation of front-line protocols.

"Call handlers suddenly saw a sharp influx of anxious calls, with a corresponding increase in erratic behaviour from the public.”
