Typical; They find a bomb, and "large crowds gather to watch". A fortnight ago, there was a hint of snow and the same tossers were emptying stores through panic buying.
I'm going to nit-pick here, but from the photo in the article this doesn't look like an 'armour piercing' bomb - more a standard 50kg HE ( note position of the fuze ). It would seem a bit odd for the Luftwaffe to be dropping AP over Central London..... ( These seem to be popular ; this is identical to the bomb found in Wembley a year or two back... )
Could have made the New Year fireworks display even more 'interesting'! By definition, there will be loads more out there. Thankfully not many actually go off although sadly, people do sometimes get hurt when they do.
