Ariana Grande benefit concert for Manchester bombing victims sells out in 6 minutes

Star-studded concert will benefit victims of Manchester Arena terrorist attack.

The concert ticket seller is also policing for scalpers trying to resell tickets.

Grande, 23, and her manager, Scooter Braun, pulled together the star-studded show in just days after the attack. Organizers announced earlier today that girl band Little Mix and pop superstar Robbie Williams will also be joining the lineup.

BBC TV, Radio and the Capital Radio Networks in the U.K. will preempt their regular programming to carry the concert.

Police say Salman Abedi, 22, was behind the suicide bombing and, on March 29, added that 16 others have been arrested in connection with the attack. Two of those people have been released without charges.

Grande suspended her tour but will resume it next month, after the benefit concert.
