The Met Police is asking all members of the public - people who live in London, as well as those who work in and visit the city - to trust their instincts and contact the Anti-Terrorist Hotline on 0800 789 321 with any information they have. No piece of information is considered too small.
"We want people to look out for the unusual - some activity or behaviour which strikes them as not quite right and out of place in their normal day to day lives." Terrorists live within our communities, making their plans whilst doing everything they can to blend in, and trying not to raise suspicions about their activities.
"They have a lot of work to do before they attack. They need money and may commit cheque, credit card and identity fraud to finance their activities.
"Terrorists use chemicals. Do you know someone buying large or unusual quantities of chemicals for no obvious reason? Handling chemicals is dangerous, and maybe you've seen goggles or masks dumped somewhere?
"Observation and surveillance help terrorists plan attacks. Have you seen anyone taking pictures of security arrangements such as CCTV? Has it made you suspicious?
"Meetings, training and planning for terrorist attacks can take place anywhere. Do you know someone who travels but is vague about where they're going?
"Terrorists use computers - do you know someone who visits terrorist-related websites?
