British police arrested a man on Friday in the suburb of Moss Side, the tenth person to be taken into custody in connection with Monday night’s Manchester attack.
Eight men are in custody now after a man and a woman were released without charge, Greater Manchester police said in a tweet.
Moreover, cases were also registered against four suspects over charges of terrorism.
A suicide bomber killed at least 22 people in a packed concert hall in Manchester, in what British Prime Minister Theresa May called a sickening act targeting children and young people.
