That was a significant police update from the Met's Stuart Bell, who spoke to reporters a short while ago.
We now know not only that this was a frightening incident for many here this morning - but tragically a teenager has been killed.
At the end of the news update, Bell said police believed this wasn’t a targeted attack - but he wouldn’t answer questions asked by reporters about whether the suspect was known to the police, and if he had previously been arrested.
"It shows the danger our police officers face every day and I thank them for their bravery," Sadiq Khan, giving a statement, says.
Metropolitan Police officers were "well aware this was a dangerous man" but they "risked their own safety to make sure others weren't injured as a consequence of this man's actions," he tells reporters.
"It demonstrates to all of us the everyday bravery of police officers in London and across the country."
Khan finishes by asking local residents to send any doorbell footage they may have to police. He says it could help officers with their investigation.
Khan continues, sending his condolences to the family of the child who died after the attack:
Quote MessageIt breaks my heart not only that this child has lost his life, but two members of our emergency services have risked their own safety to make sure others weren't injured."
Khan praises the police and other emergency services for their bravery, too.
We're heading straight to City Hall now, where Mayor of London Sadiq Khan is giving a statement about the attack.
He describes this morning's events as "devastating" and "appalling".
"I'm sure I speak for the entire city when I say our thoughts are with this young child and his family," Khan says.
Ch Supt Stuart Bell takes two questions from reporters after reading out his statement - but doesn't offer up any more details than what's in his statement.
A reporter asks whether the suspect had previously been arrested, to which Bell says he won't comment on such matters until police feel it's appropriate.
He adds that police don't believe it was a targeted attack.
With that, the Met's Ch Supt Stuart Bell thanks the press and the news conference comes to an end.
Turning to the families of those injured, Ch Sup Bell tells reporters:
Quote MessageI know the families of those involved, the local and wider community and many across London will want to know why this terrible incident occurred.
Quote MessageIt's our job to find out - and we will.
Quote MessageI am committed to providing those answers when we can and I would ask for some patience while this important work is carried out."
He thanks "not just police", but all those who responded to this morning's attack, hailing their "incredibly bravery".
Bell also reiterates that anyone with information or footage of the attack should call 101 and get in touch with the police.

He confirms that five people were injured - three members of the public and two of his officers.
One, as Bell's already said, was the boy who died. The two others "remain in hospital, but thankfully their injuries are not believed to be life-threatening," he says.
Meanwhile, both officers are also still in hospital and require surgery, but their injuries do not appear to be life threatening at this stage, Bell adds.
A 36-year-old has been arrested and is in custody, Bell tells reporters, adding that police are not looking for any other suspects in relation to the incident.
He says the man was Tasered at the scene and arrested 22 minutes after the first call was made to police, shortly before 07:00 BST.
"We do not believe there is any ongoing threat to the wider public," Bell adds.

Ch Supt Bell - speaking to reporters - says the boy's family are being supported by local specialist officers.
"Everyone at the Met is keeping them in their thoughts at this unimaginably difficult time."
He says the events of this morning are "horrific" and says he "can't begin to imagine" how those affected must be feeling.
Bell adds that his officers are working to ascertain "the full facts as a priority", and his thoughts are with the local community as that work's carried out.
Bell confirms that a 13-year-old boy, who was among the five injured this morning, has died from his wounds in hospital.
"He was taken to hospital after being stabbed and sadly died a short while after," he says.

He confirms that police have made an arrest and "are not looking for any other suspects", and says his "prayers are with those who've been injured and their loved ones".

We're hearing from more witnesses now, who saw what happened in Hainault this morning.
Chris Bates, a local resident who lives on Thurlow Gardens, tells Radio 5 Live he saw the alleged attacker being arrested:
Quote MessageHe had a big samurai sword basically. It was a huge sword. I saw it all from my bedroom window and then when he went into the driveway, a couple doors down, I ran outside and then the police Tasered him there.
Quote MessageIt’s terrible when people are going to school, work. It’s the last thing you want to hear, someone running around the local area with a samurai sword.
Quote MessageThank god I didn’t go down and get a bottle of milk from the local shop otherwise I would have met him, god knows what would have happened. Credit to the police, they were all very brave."
