The hip-hop star was performing in Trondheim on Sunday night (04Oct15) when he stopped the show after just two songs.

He walked off stage and did not return.

Organisers later tweeted an explanation, revealing the show had been cancelled due to "medical reasons".

Bronson has now taken to Twitter.com to tell fans not to worry.

"This has been one of the most satisfying tours I've ever done," he tweeted. "Had an issue the last night smh (shaking my head) but I'll be all good. Much love!!... Now it's back to work... New album coming!!!!! (sic)."
