GLOUCESTERSHIRE Police took to Twitter to send condolences to the officer who was stabbed and killed in the London attack yesterday.

One of the five people who died in the attack was PC Keith Palmer, 48, a husband and father who was stabbed and killed by the attacker.

At least 40 others were injured. 

Gloucestershire Police tweeted yesterday evening: "Our thoughts are with everyone injured & who lost their lives today in London attack including MPS officer. Our most sincere condolences."

The attacker, who was shot down by armed officers, has not yet been named by police.

The attack happened at 2.40pm yesterday when a man drove a grey Hyundai i40 along a pavement over Westminster Bridge in London, killing three people and injuring many more.

After, the car crashed into railings outside the Houses of Parliament, the attacker, armed with a knife, ran to Parliament where he was confronted by the police.

It was then that PC Palmer, who was unarmed, was stabbed and killed.

Metropolitan Police said they think they know who the attacker is and that he was inspired by international and Islamist-related terrorism.

Acting Deputy Commissioner and head of counter terrorism at the Metropolitan Police, Mark Rowley, paid tribute to PC Palmer, saying: "He was someone who left for work today expecting to return home at the end of his shift, and he had every right to expect that would happen."

Since the terror attack, Gloucestershire Constabulary have been working with police colleagues and partners to fully establish the situation in Gloucestershire and the potential threat to the people who live and work in the county.

Chief Superintendent Jo Smallwood, who is leading the force’s response said that people should not worry: “Firstly, I want to reassure anyone living, working or visiting Gloucestershire that the national threat level has not changed and we haven’t identified any threats in the county relating to the incident in London yesterday.

“However, we appreciate many people will be concerned by events and we are working with our partners to offer reassurance and support to ensure we all feel safe.

"This includes monitoring any potential community tensions or any increase in reported hate crimes.

"I ask if you are concerned about something that you contact us on 101 or via the 101@gloucestershire.police.uk email.”
