grannypiper That's not quite true. I couldn't sleep last night, so was awake and following Twitter as the whole thing unfolded.
There was a lot of anger that the incident wasn't being described as a terrorist incident, despite the fact that the attacker had been heard to shout that he was targeting Muslims. The BBC wasn't even covering it, although Sky was.
Many Muslims were pleading with others to keep calm, because feelings were obviously running high.
One reason the police were able to issue a description was that this attacker hadn't blown himself to bits. He's been named on social media, but I don't think the police have made an official announcement.
Apparently, two people are critically ill in hospital, but the man who died on the scene had a heart attack. The police are trying to establish whether the heart attack was related to the attack.
