It was confirmed later that Mr Daulby was shot by a police bullet which penetrated through the door of the synagogue in Crumpsall as armed officers opened fire on Al-Shamie – who was wearing a fake bomb vest.
A police bullet also struck another man, Yoni Finlay, who is recovering in hospital after surgery.
Two other men remain in hospital after sustaining serious injuries in the attack, including one who was stabbed in the neck and chest.
Al-Shamie walked to the synagogue on foot around 15 minutes earlier, police said, and was asked to leave due to his “suspicious” behaviour.
Doorbell camera footage obtained by the BBC showed him walking down White House Avenue a short distance away from the synagogue, where he is believed to have parked a black Kia Picanto car, at 09:22.
