The chief executive of the trade-association building where Friday’s London Bridge attack began has given an extraordinary and moving account of how it unfolded.

Toby Williamson, the CEO of Fishmongers’ Hall, spoke about the attack on the BBC’s flagship TV breakfast show, “BBC Breakfast,” on Monday, praising an employee identified as Lucasz who he said fended off Usman Khan, 28, with a narwhal tusk and allowed others to escape.

Lucasz is recovering in a hospital – Williamson said he sustained five knife wounds.

Read a partial transcript of Williamson's story about Lucasz here:

"He's the guy who cleans the glasses down in the basement, and that's exactly what he was doing when he hears this scream. The scream was so loud that, as a first-aider, he makes a choice. He goes towards the trouble. He gets there on the first floor - the building just behind me - and it's very clear that there's a bad guy, he's got two knives in his hands.

"There's blood. There's screams. There's chaos. Lucasz pulls off the wall this long stick, he charges towards the bad guy and impacts him on the chest, and there's clearly something here that is protective [points to chest], and it doesn't make any sort of impact.

"But he's buying time. He allows others to escape, to move to adjacent rooms. And that point, he's got about a one-minute, one-on-one straight combat.

"This guy, we now know by the name of Khan, he works his way up Lucasz's pole, slashing with this knife, and he takes five wounds to his left side and is going to lose some strength on that side. But he's done what he needed to do in the first instance."
