A Polish kitchen worker who battled London terrorist Usman Khan by wielding a ceremonial pike has been hailed by his boss for his life-saving courage.
Lukasz Koczocik whipped the 5ft lance off the wall when he heard chilling screams while washing glasses in the basement of Fishmongers' Hall on Friday.
The heroic worker charged at 28-year-old Khan and thrust the pike into the attacker's chest before engaging him in one minute of 'kill or be killed' combat.
Mr Koczocik was then aided by two others, one with a narwhal tusk, the other with a fire extinguisher, in battling the terrorist through the halls of the historic building.
Doorman Gary sought to stop Khan escaping into the street and maintenance man, Andy - a former policeman - was stabbed in the chest while blocking the door.

Commodore Toby Williamson, CEO of Fishmongers' Hall, told the BBC: 'He's the guy (Mr Koczocik) 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 of the building just behind me and it's pretty clear that there's a bad guy.
'He's got two knives in his hands, there's blood, there's screams, there's chaos.
'Lukasz pulls off the wall this long stick, he charges towards the bad guy, and he impacts him on the chest and there's clearly something here that is protective and it doesn't make any sort of impact.
'But he's buying time. He allows others to escape, to move to adjacent rooms. At that point he's got about one-minute of one-on-one straight combat.'
Cdre Williamson described how Khan managed to dodge and work his way up Mr Koczocik's pole, slashing five wounds into the porter's left side.
Mr Koczocik became weakened by the gashes and two other men involved in the prisoners' charity joined in the fight with a narwhal tusk and fire extinguisher.
