Story highlights Bieber has two UK concert dates this summer

Fans are begging his manager to cancel them

(CNN) For once, some Justin Bieber fans don't want to see him perform.

A group of "Beliebers" is lobbying to have his UK tour dates canceled after Monday's Manchester Arena bombing following an Ariana Grande concert that killed 22 people and left dozens more injured.

Bieber's "Purpose Tour" has dates in Cardiff June 30 and London July 2.

Some are appealing to Bieber's manager, Scooter Braun, who also manages Grande, to nix the shows.

"Next month Justin has a show scheduled in the UK, for security reasons this has to be canceled @scooterbraun," one fan tweeted. "I beg you!"
