IMAGES have been released of Manchester bomber Salman Abedi on the night of the attack.

The pictures come from CCTV on Monday when he detonated a bomb at an Ariana Grande concert in Manchester Arena, killing 22.

Police are now appealing for help to piece together what happened in the run-up to the incident.

Greater Manchester police chief constable Ian Hopkins and deputy assistant commissioner Neil Basu, senior national coordinator UK Counter Terrorism Policing, confirmed that one of the last places Abedi went was the city centre flat, and from there he left to make his way to the Manchester Arena.

It is believes the flat is “highly relevant” as the final assembly place for the device.

In a joint statement they said: “We are gathering a detailed picture of Abedi as the investigation develops and now need people to tell us if they have any information about his movements from May 18 when he returned to the UK through to Monday night.

 “The whole team are working round-the-clock. We have around 1,000 people involved in the investigation alone. In addition there are hundreds of officers and staff from Greater Manchester Police and other forces involved in the security around Greater Manchester.

“In the past five days we have gathered significant information about Abedi, his associates, his finances, the places he had been, how the device was built and the wider conspiracy.  As a result of the arrests and searches which have taken place we now have many further lines of enquiry. We already have more than 1,500 actions we are pursuing.

“This is still a live investigation which is not slowing down. Our priorities are to understand the run up to this terrible event and to understand if more people were involved in planning this attack.”
