Nottinghamshire Police's chief constable Craig Guildford has issued as a message to reassure the county following a terror attack in Westminster.
Our thoughts this evening are with all those involved in the police operation in London. In light of today's events (22 March 2017), it is really important that we come together as one, remain vigilant, and report any suspicious activity.
It has now been confirmed that PC Keith Palmer, a 48-year-old father and husband who had 15-years service with the police, died after he was attacked this afternoon, as well as four other people. None of them left home this morning not expecting to return.
Our thoughts are with the officer's family and our colleagues in the Met, as well as those members of the public who have been injured or killed.
Public safety is at the heart of what we do. It is important to stress at this stage there is no specific threat to Nottingham or Nottinghamshire, and as we go about our duties as police officers, PCSOs, police staff and volunteers, we will continue to keep you safe.
In these challenging times, we will always be the ones who run towards danger, when others run away from it.
If anyone was in London today, and witnessed what happened, or has any footage of the events, please ensure this is sent directly to the Metropolitan Police via www.ukpoliceimageappeal.co.uk
Please report any suspicious activity by calling the Anti-Terrorist hotline on 0800 789 321.
Now is the time for us all to come together, united, in the wake of such tragic events.
