Emergencies - terrorism

Reporting suspected terrorism

If you suspect somebody of being involved in terrorism in any way or are suspicious, you should report it to people who can help.

You can:

  • call 999 in an emergency
  • call the police counter-terrorism hotline on 0800 789 321
  • contact the Security Service (MI5) directly through their website

You can remain anonymous and you may save lives.

Key points

The key points are:

  • current threat level
  • threat comes principally from Al Qaida and related networks
  • Northern Ireland-related terrorism is also still a threat

Terror threat levels explained

There are five levels of threat, which are set by the MI5 and the Joint Terrorism Analysis Centre. The level they set is based on information gathered by intelligence services and the police about known or suspected terrorist plots.

The levels are:

  • critical - attack is expected imminently
  • severe - attack is highly likely
  • substantial - attack is a strong possibility
  • moderate - attack is possible, but not likely
  • low - attack is unlikely
