PHOENIX - Troubled rapper DMX was arrested in Arizona on Tuesday for violating his probation by regularly using illegal drugs during the last nine months, authorities said.

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?"

The rap star has faced continued legal trouble in Arizona, and was serving probation for throwing a food tray at a detention officer inside a Phoenix jail last year. Simmons spent 90 days in jail on drug, theft and animal abuse charges.

His attorney could not immediately be reached for comment.
