Receive critical information by signing up to @CityPolice Twitter alerts

Twitter Alerts give the City of London Police the ability to proactively notify Twitter followers with critical information during major incidents in the City of London.

We consider the use of Twitter Alerts as an urgent, tactical communication that has the ability to protect and save life. In practical terms, this means informing people of an ongoing major incident; where it is, what it is and what to do about it.

Those who follow @CityPolice and Sign up to receive Twitter Alerts can receive a text message and notification directly to their phone whenever @CityPolice marks a tweet as a “Twitter Alert".

We encourage all Twitter users who live, work and visit the City of London to subscribe to Twitter Alerts from @CityPolice.

We also recommend subscribing to other emergency services in London including the Metropolitan Police Service, London Ambulance service, London Fire Brigade and more.

What is a Twitter Alert?

Twitter Alerts are a subscription alert service for existing Twitter followers of @CityPolice. Every UK Police Service and a small number of other agencies in the UK have the ability to send Twitter Alerts.

Notifications are delivered via SMS Text Message, and if you use the Twitter App on a smartphone you’ll also receive a proactive, highlighted push notification. You can read more about the functionality on this Twitter Blog.

When will a Twitter Alert be used?

We have set an extremely high threshold for the use of Twitter Alerts. It is likely to be the first thing the Police say about a very serious situation and as such it will be a practical, informative message aimed at those in the impacted area of a critical incident.

N.B. The use of a Twitter Alert is rare with the Metropolitan Police Service yet to use the service.

Who should sign up?

We recommend anyone who works, lives or travels in the City of London to sign up to the service. If you already follow @CityPolice on Twitter it's simple to activate.

We particularly encourage the security industry and those responsible for building security to sign up, to enable effective implementation of emergency procedures in buildings, commercial premises or transport hubs.

How do I set up Twitter Alerts?

  1. Go to the Twitter Alerts setup page for @CityPolice -

  2. Sign in with your Twitter account; if you don't already have an account, you will be prompted to sign up for one.

See examples above       

Do I need a smartphone to receive Twitter Alerts?

No - as you can be notified by SMS Text Message - but you must have a Twitter account, follow @CityPolice and activate Twitter Alerts.

Does this replace established emergency protocols between Police and Businesses?

No - this is in addition tool, and quite probably, quicker than the formal procedures. It does not replace any existing protocols which should still be followed.

What if I am not from, or visit London?

Twitter Alerts are available for all UK Police Forces, other emergency services and selected agencies. Find your local force on Twitter and follow the same sign-up instructions.
