23-year-old Saskia Jones and 25-year-old Jack Merritt were graduates of the University of Cambridge, and were both involved in Learning Together.

Merritt was a coordinator of the prison program and Jones was a volunteer.

Along with Ford and Conway, local tour guide Thomas Gray, 24, and his colleague Steve helped disarm Khan.

"I've played rugby my whole life — the rule is one in, all in," Gray told The Times of London.

"My colleague Steve had the same thought and got out of his car. My thoughts were just 'stop the dude'."

A kitchen porter at Fishmonger's Hall called Mohammed, and a chef identified only as Lukasz also fought off Khan, the latter using a five-foot Narwhal tusk to help subdue the terrorist.
