Detectives investigating the Manchester Arena bomber have released more CCTV images of him as they piece together his movements after returning to the UK from Libya.

Salman Abedi left Britain on 15 April and returned on 18 May, four days before carrying out his suicide attack at the end of an Ariana Grande concert. Some 22 people were killed in the bombing.

Many of Abedi's movements and actions in the four days after he returned were carried out alone, but detectives have not ruled out that he may have been part of a "wider network".

The newly-released images of him include some with a blue suitcase that is yet to be located.

Police are appealing for anyone who saw Abedi in the Rusholme area of Manchester between 18 and 22 May to come forward.

Detective Chief Superintendent Russ Jackson, head of the North West Counter Terrorism Unit, said: "We know that Abedi left the country on 15 April and arrived back on the 18 May and we now know from our enquiries that he purchased parts for the bomb after arriving back.

"What we still need to understand is if he had any of the bomb parts in his possession before he went out of the country, this is why we are tracking his movements so carefully.

"We have made a lot of progress in this with the use of CCTV and have received some really helpful calls from the public. This has led us to the Banff Road area in Rusholme.

"We have had police officers conducting house to house enquiries but we are still not satisfied why Abedi went there and its vital we understand exactly where he went there and who he spoke to in these final days before the attack.

"We need the public's help in this. If you have previously called and have information, I would urge you to call again. We need your help as we piece together what happened in the lead up to the attack and if Abedi was helped by anyone.

"Did you see Abedi in the Rusholme area between 18th and 22nd May? Do you have any information about his movements on these dates?
