An "unprecedented" number of calls from the public during the London Bridge killings left police thinking they may be facing a "Mumbai-style" attack. The inquest into the attack heard there were more than 500 unverified reports, including claims of sustained gunfire and hostage-taking. Officers feared co-ordinated shootings and bombings, as in the 2008 killings in India. Eight people were killed with a van and knives in the 2017 London attack.
In the space of three minutes the attackers struck Xavier Thomas, 45, and Christine Archibald, 30, with a van on the bridge, before fatally stabbing Alexandre Pigeard, 26, Sara Zelenak, 21, Kirsty Boden, 28, Sebastien Belanger, 36, James McMullan, 32, and Ignacio Echeverria, 39, around Borough Market. Another 48 people were injured in the killings on 3 June 2017.
Ten minutes after Khuram Butt, 27, Rachid Redouane, 30, and Youssef Zaghba, 22, had begun their assault, they were shot dead by firearms officers. Supt Ross McKibbin, who led the first few hours of the police investigation, told the inquest at the Old Bailey officers initially believed there was "a potential" that more than three suspects might have been involved.
