A kitchen porter who fought off London Bridge terrorist Usman Khan has said he "acted instinctively."
Lukasz was working at Fishmongers' Hall as normal when the "unimaginable and trafic terrorist attack" happened.
Usman Khan launched a knife attacked at Cambridge University's Learning Together conference on prisoner rehabilitation, killing Jack Merritt and Saskia Jones, on Friday afternoon.
The Polish first aider ran towards danger, grabbing a long pole from the wall of a first-floor wall and used it to fend off the 28-year-old attacker, who was wearing a fake explosive vest.
He was stabbed several times in the attack, but has since been able to return home from hospital.
Lukasz said in a statement: "I and several others tried to stop a man from attacking people inside the building. I did this using a pole I found. Someone else was holding a narwhal tusk.
"The man attacked me, after which he left the building. A number of us followed him out but I stopped at the bollards of the bridge. I had been stabbed and was later taken to hospital to be treated. I am thankful that I have now been able to return home.
"When the attack happened, I acted instinctively. I am now coming to terms with the whole traumatic incident and would like the space to do this in privacy, with the support of my family."
He sent his condolences to the families of the Jack and Saskia and sent his and everyone affected by "this sad and pointless attack."
He told ITV News Lukasz ran towards "trouble" after hearing a "spine chilling" scream while he was washing up.
Commodore Williamson said Lukasz's bravery and quick thinking helped give others time to escape as he took on the terrorist solo.
"It's pretty clear what's happening. There's a bad guy with knives doing stuff and people fighting for their lives. Lukasz rips off the wall this long stick and charges in towards the terrorist," he said.
"He gets him, right in the chest, but it bounces off - he's clearly got some sort of protective vest, which we now know was some sort of suicide vest underneath."
"But he's (Lukasz) buying time. He's allowing others to crawl out the way and find a bit of space.
"And he's got a minute, a long, long minute - one-on-one knife fight. It's pretty brutal. The terrorist comes up, he's armed, and eventually he (Lukasz) gets five different slashes and stab wounds up here (points at upper arm)."
