London Bridge attack: ‘heroes’ who fought back include convicted murderer, a Polish chef and a plain clothes cop
- Bystanders used a fire extinguisher and a narwhal tusk to fight back against London Bridge attacker Usman Khan
- Incident a reminder of how ordinary people can take extraordinary actions to save themselves and others

Even in times of shared, senseless tragedy, an uplifting moment sometimes emerges.
Particularly striking were the weapons they used to confront the killer: a fire extinguisher and – incredibly enough – 1.5-metre narwhal tusk apparently taken from the wall of Fishmongers’ Hall when the attack began.
Remarkable video from the scene Friday shows one man spraying the fire extinguisher at the knife-wielding attacker and trying to hit him with the blunt instrument, while another uses the whale tusk to try to pin the man down.
Others ganged up on the man, wrestling him to the ground and stripping away his weapons.
Additional footage shows another man – said by some media outlets to be a plain-clothes policeman – calmly walking away from the scene with one of the attacker’s knives, making sure it could not be used to kill again.
