After lawmaker slaying, British police conduct searches as possible terrorism links probed

Police said that a 25-year-old man was arrested on suspicion of murder and is being held in custody. A knife was recovered at the scene.

Authorities say they are treating the killing as terrorism — potentially motivated by Islamist extremism. Police did not reveal the man's identity. News reports in Britain describe the suspect as a British national of possible Somali heritage.

The suspect was not on a terror watch list, authorities said. No group has come forward claiming responsibility for inspiring or directing the attack.

Early Saturday, the counterterrorism division of London's Metropolitan Police force formally declared the incident an act of terrorism. “The early investigation has revealed a potential motivation linked to Islamist extremism,” a police statement said, adding that they believed the man acted alone.

“We are not seeking anyone else in connection with the incident at this time,” police said. “As part of the investigation, officers are currently carrying out searches at two addresses in the London area and these are ongoing.”

Amess died at the scene of his wounds.

Media reports say the suspect waited in line to enter the church building where Amess was meeting with constituents and then attacked. The suspect did not flee and was quickly arrested.

Fellow politicians decried the killing of Amess as horrific — and an assault on democracy.

The attack stirred memories of the 2016 killing of Labour Party lawmaker Jo Cox, 41, who died after being shot and stabbed by Thomas Alexander Mair, a white supremacist and extreme nationalist who supported neo-Nazi ideology. Mair was sentenced to life in prison for his crimes. Another Labour Party lawmaker, Stephen Timms, was stabbed in a 2010 attack but survived.

Jo Cox’s widower, Brendan Cox, tweeted after Friday’s attack: “There is no excuse, no justification. It is as cowardly as it gets.”

The killing raised calls that members of Parliament might need more security when they meet with the public.

On ­social media, many wondered whether a more partisan Britain is more prone to this kind of violence. Other lawmakers have been physically attacked, and many have been screamed at and harassed while entering or exiting Westminster Palace.

The murder has thrown a spotlight on the political climate in Britain and how, for many politicians, threats of violence have become the norm. Between 2010 and 2016, nearly 700 crimes against British lawmakers were reported to the police. The vast majority was online abuse.

Jade Botterill, the former office manager for the lawmaker Yvette Cooper, tweeted that the office once received more than 100 death threats in a week. (In a normal week, they’d average about 50 death threats, she said.)

The Amess killing has also raised questions about whether more security is needed for politicians. The Palace of Westminster in London is guarded by armed officers and there are airport-style scanners at the entrance but there is no equivalent security for when politicians meet, on a weekly basis, with constituents.

After the murder of Cox in 2016, lawmakers were offered panic buttons, alarms and extra lighting at their homes and constituency offices. But often lawmakers meet with constituents in public spaces like churches, which is where Amess was killed.

Tobias Ellwood, the Conservative lawmaker who in 2018 tried to save a police officer who was stabbed during an attack at Westminster, said that it was time to pause face-to-face meetings until a security review concluded.

British lawmakers meet regularly with their constituents in appointments to discuss public matters and personal needs and complaints. Amess had posted online Tuesday that he was due to hold his next meeting with local residents Friday at the Belfairs Methodist Church in Leigh-on-Sea.

But many other lawmakers said that weekly in-person meetings shouldn’t stop, that they are important opportunities for dialogue. Some said conceded that, in the wake of the killing, they were nervous about their meetings, but wanted to do them anyway.

“We can’t afford for democracy to be smashed,” said the House of Commons Speaker Lindsay Hoyle.

Prime Minister Boris Johnson paid tribute on Saturday to Amess at politician’s home constituency in Leigh-on-Sea. Johnson laid flowers outside of Belfairs Methodist Church, which is where Amess was fatally stabbed. He later tweeted a picture of a card he wrote to “a much loved colleague and friend.”

The Home Secretary Priti Patel said Amess was “a man of the people” who died doing the job he loved.

John Lamb, a local councilor and friend of Amess’s, said the death has hit the community hard. Speaking to The Washington Post from outside the cordon at the church, where floral tributes were amassing, he said that “it will be very difficult to get over this.”

Amess was a “devout Roman Catholic who respected all religions,” he said.

He described his late friend as a “a genuine person who was trying to help the community all round,” including holding a tea each year for centenarians.
