"A High Court judge ordered his release this evening. He has been allowed entry into the UK having been detained all day at London City Airport," said a spokeswoman for concert organizers RockCorps.  She said his appearance at the event would depend on the outcome of a judicial review due to be held on Friday.  "We're very hopeful he'll be playing the show," she added.  The organization enlisted the services of Ludacris to replace Busta if he is not allowed to perform..

A hearing is likely to take place today (9/26) in which Busta’s legal team will challenge the UK government’s attempt to refuse him entry, reports the Associated Press.

Stephen Greene, co-founder of RockCorps, said: "We're shocked at this sequence of events and this treatment of Busta.

"Orange RockCorps has inspired thousands of young Brits to help their community, get involved and make a real difference through a love of music.  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," said Greene.

The Home Office said previous criminal convictions and a person's character and conduct were assessed before an individual was allowed into the country.

Busta has never served any time in prison, and has completed community service for his convictions.
