Report anything suspicious
The terrorist threat is real and there's no room for complacency. You should remain alert and aware of your surroundings at all times.
If you see or hear something that could be terrorist related, act on your instincts and call the police, in confidence, on 0800 789 321 or visit gov.uk/ACT. Anonymity will be assured and what we are told will always be secure.
Even if you’re unsure what to do in an emergency, act. If you've seen someone acting suspiciously, a vehicle out of place or an unattended package or bag, immediately move away and call 999.
