A SECURITY guard who fought to protect victims of a terror attack is suing for more than £200,000.
Gareth Watkins threw himself against a door in a bid to halt knifeman Usman Khan’s rampage at Fishmongers’ Hall, London Bridge, in 2019.
The hero, 54, shielded wounded Jack Merritt, 25, who later died.
He grabbed a fire extinguisher and followed Khan outside to save passers-by.
Lawyers say the RAF vet got PTSD and lost his job.
Khan, who also killed Saskia Jones, 23, was shot dead by cops.
London high court papers show Mr Watkins is suing Fishmongers and the Ministry of Justice.
His lawyers say Khan’s trip to London was not properly risk-assessed.
Khan, 28, had been jailed in 2012 for his role in a plot to bomb the London Stock Exchange.
But 11 months after his release he travelled to an offender rehabilitation event in London in November 2019, carrying a bag of knives.
Khan was not searched on arrival and went on to kill Jack Merritt, 25, and Saskia Jones, 23.
Three others were wounded.
Lawyers say the failures left Watkins suffering “pain, injury, loss and damage”.
