A dispersal order is a police power that tells people to leave a specific area and not come back for a set period, usually to prevent anti-social behavior, disorder, or crime. If someone ignores it, they can be arrested.

Quick meaning

In plain English, it means police are saying: “Move on from here now.” It is often used when a crowd, group, or ongoing situation is causing nuisance, harassment, alarm, or distress.

Common use

  • To break up groups causing trouble.
  • To clear an area during unrest, protests, or disorder.
  • To stop behavior police believe may lead to crime or anti-social behavior.

Time limit

In the UK context shown by the sources, a dispersal direction can last for up to 48 hours , depending on the situation and authorisation.

Example

If police declare a dispersal order near a street gathering, they can require people to leave the area and not return during the order period.

If you want, I can also explain how it differs from a curfew or public-order dispersal notice.
