Busta Rhymes detained at London airport

Busta Rhymes has been refused entry to the UK because of "unresolved convictions" in the US.

The rapper arrived in England this morning to perform at a charity gig tomorrow, but was detained at London's City Airport, the BBC reports. The 36-year-old is now being held while officials debate whether to grant him entry.

5,000 fans are expecting to see Rhymes perform at RockCorp along with Feeder, John Legend, The Automatic and Guillemots. They all obtained tickets for London's Royal Albert Hall by spending four hours volunteering in community projects.

Rhymes was allowed into the UK to launch the event on August 17.

RockCorps co-founder Stephen Greene 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," he said.

Greene added that rapper Ludacris is flying in from the US and will replace Rhymes on the bill if necessary.
