London attack: Seven held after armed police raids per BBC News

The BBC report on the latest terrorist atrocity in the UK http://www.bbc.co.uk/news/uk-39363297 includes this police plea:

'In a statement made outside Scotland Yard, Mr Rowley said: "The inquiries in Birmingham, London and other parts of the country are continuing."It is still our belief - which continues to be borne out by our investigation - that this attacker acted alone and was inspired by international terrorism.

"To be explicit, at this stage we have no specific information about further threats to the public.

"He said he would not name the bridge victims yet, who were "a mix of nationalities", and urged journalists not to publish the attacker's name while searches were continuing.'

So the attacker's name shouldn't be published? I don't know what it is but I can probably guess what sort of name it is.
