Story transcript

Daily Mail reporter QuentinLettswas working in his London office when he witnessed an attacker staban officer and then get shot dead by police outside the U.K. Parliament on Wednesday.

"I could see all this and it was very bizarre to be watching this in real time and to be separated from it only by a pane of window glass and yet to know what was happening out there was blood and guts," Letts told As It Happens host Carol Off from his office, which as of Wednesday afternoon, was still on police lockdown.

"We were all told to move away from the windows, but we ignored that. We're journalists."

"We first knew that something was awry when weheard a banging, which sounded like a car crash." Letts said. "We looked out the window and we saw members of the public, pedestrians, running in panic and that was an indication that things were not right."

That's when he spotted a man in dark clothes, whom Letts described as "thick set" and between the ages of 40 and 50, storming toward the gates of Parliament.

The man started attacking the twopolice officers posted at the gatewith what appeared to be a stick, about two feet long, "likehalf a broom handle," Letts said.

"One of the yellow-jacketed policemen detached himself and got away from him, but the other, I'm afraid, couldn't get away from him and was attacked while he was doing his job, just trying to say to this man, 'No you can't come in here,' he said.

Then the attacker tried to enter Parliament, Letts said, but was shot dead by plainclothes officers.

"He fell instantly," Letts said."Itell you, you can't have people doing this sort of thing. Disgraceful."

MP: 'We heard shouting and then gunshots'

Meanwhile, while Lettswitnessed every graphic detail from his office just under Big Ben, Conservative MP David Davies was in the thick of it, but saw nothing.

He was walking outside between parliamentary buildings when shots rang out and he dropped to the ground, he said.

"We heard shouting and then gunshots," Davies told As It Happens."It was literally happening yards from where I was but I didn't see anything."

Security guards quickly escorted Davies and other lawmakers and staffers toa safe location in the Houses of Parliament,where he remained in lockdownWednesday afternoon.

Davies said he and the others are remaining calm.

"There's no sense of panic. There's a sense of concern," he said. "It's the people outside, actually, I'm worried about."

Letts also remained stoicamid the chaos.

"One can over-hype the sense of panic and the sense of fear. I don't think there's that.I think there's probably a bit of a sense of anger and outrage among the people at what's happened. But you know, if there are maniacs and they attack us, well, we have to try and continue, while defending ourselves, to lead some sort of life," he said.

"We have to let our Parliaments be open. This is the whole point if politics is that people have access to their Parliament. And once you stop that, then you lose something of the very values that these people seem to very much to dislike."
