Three men arrested in connection with the Manchester terror attack have been released without charge.

The men aged 20, 24 and 37 were among 16 people arrested by police - 11 now remain in custody.

More than 1,000 officers are working on the investigation to piece together what happened and whether others worked with 22-year-old bomber Salman Abedi.

The suicide attack after an Ariana Grande concert at Manchester Arena killed 22 people and injured dozens of others.

Detective chief superintendent Russ Jackson said the release of potential suspects "can be expected in investigations of this nature as we corroborate accounts that have been provided."


He said there had been "huge progress" in the investigation and it was "vital" to ensure that Abedi had not been part of a "wider network".

DCS Jackson said: "Much of the investigation has been painstakingly working through Salman Abedi's last movements.

"We have done this by examining his movements on CCTV and other interactions he has had whether it be with people or the phone calls he has made."

He added: "With specialist support we have also have a good understanding of the likely component parts of the bomb and where these came from.

"Our inquiries show Abedi himself made most of the purchases of the core components and what is becoming apparent is that many of his movements and actions have been carried out alone during the four days from him landing in the country and committing this awful attack."

Earlier, officers investigating the attack searched a home in Wigan and the bomb squad was called out for the second time in five days.

Residents in Springfield Street, Swinley, were asked to leave their homes but were allowed back in after an hour.

On Monday, Greater Manchester Police released a photograph of Abedi with a blue suitcase in the days before the May 22 attack.

The 22-year-old had a "relatively minor" criminal record as a teenager but he was not known to police for holding extremist views, Greater Manchester Police chief constable Ian Hopkins said.
