MI5 was last night investigating Brenton Tarrant over possible links to far-right extremists in Britain.
Spies are reviewing the Australian’s 74-page manifesto, a Whitehall source told The Times.
Tarrant said he was inspired by Darren Osborne, who drove into worshippers outside Finsbury Park Mosque in North London in 2017
Scotland Yard’s Assistant Commissioner Neil Basu, head of counterterrorism, said there was “no intelligence linking these appalling events to the UK”.
Meanwhile, security at mosques across Britain was stepped up yesterday over fears of a copycat attack. Police increased patrols and offered advice.
Col Richard Kemp, former chair of the Government’s Cobra group, admitted: “A New Zealand type attack has long been considered.”
