Busta Rhymes has been detained after landing in London City Airport. The hip-hop star is reportedly being refused entry into the Britain, where he is scheduled to perform at the RockCorp charity concert at Royal Albert Hall on Friday.

According to reports, immigration officials wanted are holding the 36-year-old due to “unresolved convictions” in the US.

Stephen Greene, the co-founder of RockCorp, said he was “shocked at this sequence of events and this treatment of Busta”.

“He has the necessary work-permit and has been in the country twice already this year, so we’re a little puzzled that a question mark is now being placed over his ability to enter the country to perform to volunteers.”
