A Baltimore County judge has issued bench warrant for the arrest of rapper Kevin Barnes, known as “Chopper” from MTV?s “Making the Band 2.”

The warrant alleges that Barnes, a former protégé of entertainer Sean “Diddy” Combs, did not fulfill the terms of his probation stemming from a March armed robbery conviction, said Elizabeth Bartholomew, spokeswoman for Maryland?s Division of Parole and Probation.
