LONDON, April 30 (Xinhua) -- The suspect of a stabbing incident in Golders Green, north-west London, was known to Britian's official counter-extremism scheme in 2020, according to British media on Thursday.

The suspect, a 45-year-old British man, was born in Somalia, Metropolitan Police confirmed late on Wednesday.

He was known to the Prevent, the country's official counter-extremism scheme, and was subject to a Prevent referral in 2020, British media quoted Metropolitan Police as saying.

Metropolitan Police Commissioner Mark Rowley said the suspect has "a history of serious violence and mental health issues."

On Wednesday, Two people -- aged 76 and 34 -- were stabbed in the Golders Green area, before the attacker was tasered and arrested by the attending police. The incident was later declared "a terrorist incident" by the British counter-terrorism police.

British Prime Minister Keir Starmer called the incident "utterly appalling," promising that his government would act to make local Jewish community feel safe and fight antisemitism. But he found himself facing heckles from angry protesters when visiting the neighborhood on Thursday.

The government will invest an extra 25 million pounds (33.8 million U.S. dollars) to increase police patrols and security to for the protection of the Jewish communities, according to Britain's Security Minister Dan Jarvis on Thursday. ■
