Looks to have happened at 10:33 p.m.

It might be ten hours until we learn more than ‘knife’ and a ‘man.’

It has been reported elsewhere that the man was dark skinned and possibly of north African descent. Also, Britain’s counter-terrorism authorities, the division of Scotland Yard known as SO15, have been called in.
