So, it seems that there isn't anything chemical/biological to worry about - so no doubt the Decontamination team are all disappointed...

The police commisioner has told all us Londoners to carry on as normal, but to avoid the affected areas.

The last I heard was that some of the team were looking at a "white powder" incident - but we get a couple of them a week, so it's unlikely to be anything serious.

Once more, most Londoners will look at what happened today, shrug their shoulders and make a cup of tea.

(Something I'm going to do now...)
