Suspicious activity

Every year thousands of reports from the public help the police keep communities safe from terrorism.

Suspicious activity could include:

  • taking delivery of guns without a licence
  • stockpiling chemicals, gas cylinders or fertilisers for no obvious reason
  • taking photos of security arrangements
  • posting content online that glorifies terrorism.

Check the government's Action Counters Terrorism website for more details about suspicious activity, as well as videos and further advice.
