Two members of the public have died in the attack.

Zuleika, I saw the footage on the news tonight, and possibly what some people are getting confused with is 'the man with the knife running away' bit.

The person the public pinned down had got the knife.
It was confiscated from him quickly and passed to another chap to get it out of reach.
The man holding the confiscated knife was a member of the public trying to help.
But when it looked the 'baddie' might detonate a suicide bomb, and it was obvious the police were about to open fire, the man with the knife quite rightly legged it to a safe distance away.
That is why a man was seen running away with a knife.
I think some might have misinterpreted what they saw.

I think the man holding the knife was very brave.... and it's lucky he wasn't shot dead in the confusion.

I'm not sure if I would be first to attempt it but if he was down, I would gladly stamp on his face a few times.

I hope that I would try to stop him killing or maiming somebody.

Who knows?

But many will chose to cross the road and walk past on the other side.

I just hope i'm not like that!
