"He had knives in both hands and, upon seeing me with the narwhal tusk, pointed at his midriff." There, Darryn Frost recalls, was what he thought was a suicide vest.

The civil servant has told for the first time how he confronted London Bridge knifeman Usman Khan, 28, before grappling with him and pinning him to the ground.

Khan, who was wearing a fake explosive device, was shot dead by police after killing Saskia Jones and Jack Merritt.


During the attack, which began at a prisoner rehabilitation event inside Fishmongers' Hall on 29 November, Mr Frost, 38, said he grabbed a narwhal tusk on display in an effort to protect himself and others.

He then chased Khan onto the bridge, where footage captured him and fellow members of the public fending off the attacker.

Mr Frost's identity was unknown until now. The South African-born Londoner, who works in communications at the Ministry of Justice, told the PA news agency how he was attending the rehabilitation event with colleagues when he heard a commotion downstairs.
