Three brave men are being praised for their courage in chasing down and fighting a terrorist who killed two people and injured five others with a knife on London Bridge on Friday.

A Polish chef known as Lukasz was one of the men who fought the attacker. In dramatic footage of the fight, Lukasz can be seen wielding a narwhal tusk he found at the nearby Fishmongers’ Hall and thrusting its sharp point towards the terrorist.

Another courageous man sprayed and blinded the terrorist in the face with a fire extinguisher. In the end, the terrorist was detained long enough by civilians for police to arrive on the scene and shoot him dead to put an end to the madness.

While his name won’t be published here, the terrorist is being claimed by the Islamic State as one of their own, and he had been previously jailed in the UK in 2012 for terrorist offenses.

Victims killed in the attack include Saskia Jones, a 23-year-old University of Cambridge graduate, and 25-year-old Jack Merritt, a fellow graduate of and course coordinator at the University of Cambridge.

Three other victims are being hospitalized.
