The leader of Wandsworth Council has expressed his “deepest condolences” following the “outrageous and shocking” terrorist attack in Islington and promised extra patrols in the borough.

One man has died and eight people have been taken to hospital after a van was driven into pedestrians near Finsbury Park mosque.

The van driver, described by eyewitnesses as a large white man, was detained by members of the public after the attack in Seven Sisters Road at 12.20am on Monday.

Councillor Ravi Govindia said: “Our city is being tested yet again in the cruellest possible way and I want all those affected to know that Londoners stand with you at this incredibly difficult time.

“This horrendous incident will be a cause of great concern to Wandsworth’s Muslim community and the council’s community safety team is now working alongside the police and other authorities to visit local mosques and religious venues to review and strengthen security arrangements.”

The council leader confirmed addition police resources have been put in place and there will be “visible reassurance patrols for the foreseeable future” in the borough.

This includes additional police vehicles that will be focusing on religious venues across the borough.

Cllr Govindia added: “Following last night’s terrorist attack the people of Wandsworth have once again responded with concern, kindness and a show of even greater unity. This is something we should all be very proud of.”
