Counter-terror police have carried out a controlled explosion as they searched a Manchester property in connection with Monday's deadly suicide attack which claimed 22 lives at a music concert.
Locals in Moss Side, south of the city centre, reported hearing a "loud bang" at around 1.45am (local time) on Thursday.
Six men and one woman are in custody following a series of raids across Manchester, Wigan and Nuneaton, Warwickshire, following the attack by bomber Salman Abedi, which also left 64 people injured.
Greater Manchester Police confirmed another search of an address had taken place, although there were no reports of any further arrests.
"This morning (Thursday 25 May 2017) we have been carrying out searches at an address in the Moss Side area during which a controlled explosion took place," the police said in a statement.
"These searches are connected to Monday's attack on the Manchester Arena, but this is a fast, ongoing investigation and we are keeping an open mind at this stage.
"As it stands, six men and one woman have been arrested in conjunction with the investigation and remain in custody for questioning."
The explosion was heard in the neighbouring areas of Rusholme and Fallowfield, with concerned locals taking to social media.
One wrote: "Does anyone know if the loud bang heard at 1:45amish this morning in/near Moss Side & Rusholme was an un/controlled explosion?"
