Any information passed to the Anti-Terrorist Hotline is treated in the strictest of confidence and is thoroughly analysed and researched before, and if, any police action is taken.
Terrorists have a lot of work to do before they attack. They need to plan and prepare; buy and store materials; and fund their activities.
Terrorists live within our communities and blend in. However, behind closed doors they may be storing bomb making materials or meeting others to plan attacks. Are you suspicious of a property where there is unusual activity or strange comings and goings that don't fit day-to-day life?
Terrorists use surveillance to help plan attacks. Have you seen anyone taking pictures or filming CCTV cameras or making notes about other security arrangements? Has it made you suspicious? If you have seen this or know someone who takes an unusual interest in security measures, we need to know.
Terrorists need communication. They communicate with others to plan meetings or buy materials and chemicals. To avoid possible detection they use multiple anonymous pay-as-you go mobile phones and swap SIM cards and handsets. If you are suspicious about someone who uses phones in this way, we need to know.
We are asking members of the public to trust their instincts and pass on information which could help stop terrorists in their tracks.
If you suspect it, report it.
