The Essex Police force said officers were called to reports of a stabbing in Leigh-on-Sea just after noon Friday. It said “a man was arrested and a knife recovered.

“We are not looking for anyone else in connection with the incident and do not believe there is an ongoing threat to the wider public,” police said.

Sky News and others said Conservative lawmaker David Amess was attacked during a regular meeting with constituents at Belfairs Methodist Church in Leigh-on-Sea, a seaside town east of London.

There was no immediate word on his condition.

Amess’ London office confirmed Friday that police and ambulance had been called, but had no other details.

Amess has been a member of Parliament for Southend West, which includes Leigh-on-Sea, since 1997, but has been a lawmaker since 1983.

Politicians from across the political spectrum expressed shock. Labour Party leader Keir Starmer tweeted that it was “Horrific and deeply shocking news. Thinking of David, his family and his staff.” Violence against British politicians is rare, but in June 2016 Labour Party lawmaker Jo Cox was fatally stabbed and shot in her northern England constituency. A far-right extremist was convicted of her murder.

Two other British lawmakers have been attacked this century during their “surgeries,” regular meetings where constituents can present concerns and complaints.

Labour legislator Stephen Timms was stabbed in the stomach and injured in May 2010 by a female student radicalized by online sermons from an al-Qaida-linked preacher.

In 2000, Liberal Democrat lawmaker Nigel Jones and his aide Andrew Pennington were attacked by a man wielding a sword during such a meeting. Pennington was killed and Jones injured in the attack in Cheltenham, England.
