UK police declared the fatal stabbing of Sir David Amess a terrorist incident as the investigation into the incident continued.
The Conservative member of the UK Parliament, from Southend West, was stabbed at a constituent meeting at a church and died at the scene.
“The early investigation has revealed a potential motivation linked to Islamist extremism,” UK police said in a statement overnight.
Police arrested a 25-year-old man on suspicion of murder after the attack, which happened around midday on Friday in the English coastal town of Leigh-on-Sea.
UK police say it is believed the man acted alone but enquiries into the incident are being carried out with police carrying out searches at two addresses in the London area.
Boris Johnson said he was “full of shock and sadness” at the death of the MP who was “killed in his constituency surgery, in a church, after almost 40 years of continuous service to the people of Essex and the whole of the United Kingdom.”
“He was one of the kindest, nicest, most gentle people in politics,” he added.
British politicians paid tribute to the MP and expressed their shock over the incident.
It comes five years after Labour MP Joe Cox was fatally stabbed in her constituency. A far-right extremist was convicted of her murder.Internet Explorer Channel Network
