“The attacker, I can confirm, died at the arena. We believe the attacker was carrying an improvised explosive device which he detonated causing this atrocity,” Ian Hopkins, chief constable of Manchester police, told a news conference on Tuesday.

“We believe, at this stage, the attack last night was conducted by one man,” he said, adding that an investigation is underway to establish if the man was part of a network.

Meanwhile, the death toll has risen to 22 people, including children, the police chief said. Fifty-nine others were injured in the blast.

The police are treating the explosion as a “terrorist incident,” Hopkins said.
