Whttington Hospital 'bomb scare'

Have just been reading about this over on Twitter. It is clear that there are police surrounding the hospital and that some local buildings have been evacuated, but nobody seems to be sure what's happening. At least one person has claimed it is a 'false alarm' while most local papers still say it's 'ongoing'.

I have a lot of friends in the area and would like to know if anyone has further information. Thanks.
