Police arrest 23-year-old youth in connection with Manchester attack

Quoting police, the report said the man was arrested in south Manchester Tuesday, a day after the explosion killed 22 people and injured 59, many of them teenagers.

However, police did not provide the  details.

British Prime Minister Theresa May has postponed her campaigning for the general elections and will chair a meeting of Cobra committee later, the BBC reported.

"All our thoughts are with the victims and the families of those who have been affected," May was quoted as saying in the media.

Following the attack, the area was cordoned off, thereby disrupting train services.

Andy Holey, an eyewitness was quoted as saying by BBC, "As I was waiting, an explosion went off and it threw me about 30ft from one set of doors to the other set of doors."

"When I got up I saw bodies lying on the ground. My first thought was to go into the arena to try to find my family.

"When I couldn't find them, I went outside with the police and fire and looked through some of the bodies to try and find my wife and daughter," he added.

Holey eventually managed to find them in a safe state.

Some eyewitnesses have also claimed the incident as a bomb attack.

"It was definitely a bomb. It was definitely in the foyer," Emma Johnson told BBC Radio Manchester.

"The whole building shook. There was a blast and then a flash of fire afterwards. There were bodies everywhere," Emma added.
