The rapper, whose real name is Earl Simmons, told a probation officer that he used cocaine and was not complying with the terms of his treatment plan, Maricopa County Sheriff Joe Arpaio told Reuters.
He faces five counts of violating probation.
Simmons was booked into a Phoenix jail late Tuesday afternoon and was isolated from other inmates, sheriff's officials said.
"We would hope that he is finally sent to prison," Arpaio said. "We've arrested him five times already. How many times do you have to violate the law?"
