An explosion rocked an Ariana Grande concert in England Monday, sending scores of people running for safety and nearly 2 dozen are dead in what may be an act of terrorism.
The concert was held at the Manchester Arena ... the explosions occurred at the end of Grande's concert. One of the concertgoers tweeted, "Just ran from an explosion, genuinely thought were going to die."
The suicide bomber at Ariana Grande's concert did not act alone ... according to police who say they've nabbed another man in connection with the attack.
Greater Manchester Police say they arrested the 23-year-old man Tuesday. They have not said what his connection is to the bomber, who was one of the 22 killed when he detonated the "nail bomb" Monday night in the rotunda at Manchester Arena.
The bust seems to point to the bomber not acting as a so-called lone wolf.
ISIS has claimed responsibility for the attack, claiming it was executed by one of its "soldiers."
Ariana is inconsolable, and said to be "in hysterics" after the bombing. As one source said, she's incapable of performing for anyone. She and her team, we're told, are also deeply concerned about security.
Ariana's manager, Scooter Braun, said, "We mourn the lives of children and loved ones taken by this cowardly act," adding, "We ask all of you to hold the victims, their families, and all those affected in your hearts and prayers."
Our sources say Ariana is not concerned with her shows now, she and her team will re-evaluate the touring schedule when she's emotionally ready.
Bodies were strewn in the rotunda outside the seating area where Ariana Grande had just finished her performance at the Manchester Arena.
As we reported, at least 22 people were killed ... the victims as young as 8. 59 people were injured from the nail bomb that exploded in a backpack.
The fatalities occurred from a stampede that followed.
