LONDONERS are being urged to trust their instincts to help police in the fight against terrorism and potentially save lives.

The Met has launched a five week publicity campaign this morning (February 18) to let everyone who works, lives and visits the capital know they have a role to play to counter the terrorist threat.

It’s probably nothing, but . . . encourages anyone who sees or hears something they think could be terrorist related to call the anti-terrorist hotline on 0800 789321.

Deputy assistant commissioner Stuart Osborne, senior national co-ordinator counter terrorism, said: “Protecting Londoners from terrorism is one of the top priorities for the Metropolitan Police Service.

"The threat, whether it is from Al-Qaeda inspired groups or individuals, dissident Irish republican groups or other violent extremists, is still a real and serious one.

"You know the area where you live better than anyone else so we ask you to be vigilant, trust your instincts and tell us about anyone or anything you see which is out of place in your normal day to day lives.

"No piece of information is considered too small or insignificant.

“Our specialist officers would rather take lots of calls which turn out to have an innocent explanation than miss out on a vital piece of information.

"We understand that you may have concerns about speaking to the police - possibly because you think your friends or family may find out or because you don't want to get people into trouble.

“However, all calls are treated in the strictest confidence and information is thoroughly assessed before - and if – any further action is taken.

"Please help us to create a difficult environment for the terrorist.

“Your call really could save lives.

"Terrorists live among us while they are planning their attacks so we need the help of all our communities to pass on any suspicions to the Anti Terrorist Hotline on 0800 789321.”

In an emergency people should always dial 999.
