Amy Coop, who was at Fishmaongers’ Hall in London when today’s terror attack happened on London Bridge, witnessed a man inside the room grab a 5-foot long narwhal tusk from the wall and ran outside to attack the terrorist:

A guy who was with us at Fishmongers Hall took a 5’ narwhale tusk from the wall and went out to confront the attacker. You can see him standing over the man (with what looks like a white pole) in the video. We were trying to help victims inside but that man’s a hero #LondonBridge — Amy Coop (@theamycoop) November 29, 2019

You can see the tusk in the video:

Update: We just found this tweet with the video embedded. Awesome:

New footage of yesterday's terror attack on #LondonBridge. Three members of the public armed with a fire extinguisher and a Narwhal tusk take the attacher down. Heroes. pic.twitter.com/8yGBPaGtbL — Darren of Plymouth ?? (@DarrenPlymouth) November 30, 2019

A second man used a fire extinguisher to confront the terrorist:

Not making light of the wretched stabbings in London. But two people who bravely challenged the attacker used a narwhal tusk from a nearby fishmongers hall and a fire extinguisher to halt the attack. Quite remarkable, I believe. https://t.co/u3cFm09YWl — Chuck Bartels (@cbartelsLIT) November 29, 2019

This has to be a first, right?

First instance of narwhal tusk used to subdue a terrorist, at least that I am aware of. https://t.co/VjeBlhXeNF — Terry Glavin (@TerryGlavin) November 29, 2019

According to the Daily Mirror, the terrorist was recently released from prison for being a terrorist:

#LondonBridge terror attacker was attending a Cambridge University conference on prisoner rehabilitation being held at Fishmongers' Hall and "threatened to blow up" the building. https://t.co/SjPAv9oiDE — Daily Mirror (@DailyMirror) November 29, 2019

From the Daily Mirror:

The knife-wielding terrorist who killed two people before being shot dead by police was known to authorities and had connection to Islamist terror groups, sources understand. He was released from prison about a year ago after agreeing to wear an electronic tag and be monitored by authorities, the Times reports. The paper said he was attending a Cambridge University conference on prisoner rehabilitation being held at Fishmongers’ Hall and “threatened to blow up” the building.
