London Ambulance service has declared a major incident.

A BBC reporter at the scene says he saw a struggle between a group of men and heard shots being fired.

The bridge was being sealed off on.

Members of the public are being directed away from the area.

Emergency services are at the scene.

We can show you some off the latest images sent into us now by someone who works nearby.

They show people running across the bridge in panic.

As you might expect.

Reuters, a reputable news agency, is saying that they understand that somebody has Bean stabbed in the area on that Police have, as Andy More, our correspondent was saying, have detained a suspect.

Other reports are suggesting they have shot a suspect.

Let's talk now to someone who is in the area.

Thomas Dunford.

Thanks so much for joining us here on BBC news at Mr Dunford.

What can you see at the moment?

Well, we've just been moved.

So I was on 55 King William Street, which overlooks the bridge.

So I saw two bodies get dragged from the bridge.

One guy was getting resuscitated, but my understanding, I think, passed away a sheet over him.

But you know that right from the building just down toward our bridge on.

Then I just seen five on the territory.

Will ban uh, June part.

It's worth therefore rewinding.

We understand this incident started to involved unfold just before two o'clock this afternoon local time here in London.

Where were you at that point?

At that point, I was in my office.

I saw ever been outside my office in terms of the peace plan.

Then I saw the bodies get checked out to on police.

Running towards London was done on, I think Brit Brit.

Sure we had gunshots, right?

Because I was going to ask you what?

What you thought you might have heard?

We did speak to another eyewitness a little earlier Who thought that they had heard as many as seven or eight shots?

Does that sound similar to your experience?

Way?

Yes.

On then emergency services Very quickly on the scene.

We know.

The London Ambulance Service has declared a major incident on and people ushered off the bridge very quickly.

What was the mood like, where people fairly calm Or, uh what people Rather more panicking, Uh, panicky.

I mean, those people in the cafe, off farm, a jays and a first aid closed all the doors within the peace, open the doors and made everybody sort of spring cow.

I'm all at once was very panicky, but by well, they got everybody out of the area pretty quick.

Thomas, we're looking as you speak at a new image that you've sent into us, which I assume you filmed on your phone.

Can you just exact explain to us exactly where that is in relation to the bridge from that image?

If you were to go to the left, that London bridge.

Right.

So that's pretty much looking at the end of month.

And when did you take this photograph?

When did you take this film?

Um And so if you were to look at the scene now, does it still look like that?

I've been Usher have been evacuated from the from the area now, so I'm now about average, right?

Yes.

You said on when you say you were ushered away from the area.

What was that by the police?

And if so, what did they say to you?

So they communicated with the receptionist downstairs in my office to get a bus that we needed to evacuate the building.

And then we got down sprint, right?

Okay, well, look, it must be it must be Roll the frightening Do stay in touch with this.

But for now, Thomas dumping.

Thanks so much for getting in touch with us.

Let's talk now to Mike King.

No, let's talk in the Meanwhile, we wait to talk to my king, who I also think is in the area.

Let's bring in our correspondent Andy Moore, who is sitting with me watching these pictures onder keeping abreast of any developments.

What are you seeing in hearing Andy?

So, first of all, the official information for the Metropolitan Police, it's worth repeating.

They were called to an incident a 1 58 They said it involved a stabbing.

They say several people have been injured and they talk about a man being detained London Ambulance service, saying they've declared a major incident.

So I'm looking through lots of eyewitness video from from the scene now I'm looking at some some other video, which shows what appears to be a member of the public.

As I said, Somebody in civilian clothes.

For all we know, it may be a police officer who who's in civilian clothes.

We just don't know, but appears to be a member of the public, wrestling with a man on the floor.

The men on the floor appears to be dressed in black clothes, appears to be bearded.

The member of the public who's who's wrestling with him is pulled off on.

Then the police fire a number of shots, so it is worth remembering.

Here we go.

Sorry, Weaken.

See some of that of video now exactly what I was talking about.

So I mean, it was our correspondent John McManus, who said it appeared to be a fight.

We can see the member of public being pulled off.

Then it's just after this that the man is shot and then you can see Yes, we're seeing it again.

So that member the public see there is being pulled off.

Men on the ground of them were not showing, obviously the moment of shooting.

But then the man is shot on disabled.

And after that it's interesting that the armed police stand back some distance.

They don't administer any first aid to the men on the ground.

They're obviously concerned that there may be explosives on the man.

There may be some further danger.

This hasn't officially being declared a terrorist incident, but it's worth remembering.

This is on London Bridge.

The scene of the terrorist incident in 2017 which involved stabbings, which involved the terrorists being shot, said there are some elements that are certainly similar.

Okay, Andy more.
