Police tell the BBC that 35-year-old suspect Jihad Al-Shamie was on police bail for an alleged rape when he carried out a car ramming and stabbing attack at a Manchester synagogue on Thursday
Counter Terrorism Policing say that he may have been influenced by "extreme Islamist ideology"
Adrian Daulby and Melvin Cravitz were killed in the attack, while three people - including Yoni Finlay, who was also shot by police while stopping the attacker - remain in hospital
Daulby's family describe him as a "hero", who died during "the act of courage to save others"
The family of Melvin Cravitz say he was a "kind, caring" person who "would do anything to help anyone"
Police believe that Daulby's injury may have been sustained "as a tragic and unforeseen consequence of the urgently required action taken by our officers"

Reporting from the scene
I’m currently standing at the police cordon just on the edge of Middleton Road, where the incident has taken place.
Helicopters are flying overhead, we’ve got sirens going every two minutes and police have cordoned off the site. I’ve seen paramedics and the fire service all on site.
A major incident - and Operation Plato - has been declared.
Lots of members of the public, including members of the Jewish community, are gathering round now to see what has happened.
Understandably, this is a huge shock to the people of Greater Manchester this morning.

Police tell the BBC one of those injured is a security guard.
To recap, police say four people were hurt in the attack and the suspect was shot. The Manchester mayor says the suspect is believed to be dead, but their condition hasn't yet been confirmed.

BBC Verify has been looking at footage linked to the attack at a synagogue in Manchester.
The video shows armed police officers outside a synagogue on Middleton Road standing in front of a person lying on the ground.
Another person outside the synagogue is also lying on the ground surrounded by blood.
We matched images from the footage with what we could see on Google Maps to verify the location.
We've just had this statement from Prime Minister Keir Starmer:
"I’m appalled by the attack at a synagogue in Crumpsall.
"The fact that this has taken place on Yom Kippur, the holiest day in the Jewish calendar, makes it all the more horrific.
"My thoughts are with the loved ones of all those affected, and my thanks go to the emergency services and all the first responders."

Police said they declared "Plato" moments after first hearing about the incident.
Operation Plato is a set of responses by the emergency services to large-scale incidents including "marauding terrorist attacks".
When police declare Operation Plato, the other emergency services such as the ambulance service then have protocols that they follow.
For example, NHS trusts will activate their major incident plans.
