DMX has been arrested for violating his probation.

The rapper - real name Earl Simmons - was taken into custody in Arizona, US, yesterday (09.03.10) and charged with five counts of probation violation.

Sherrif Joe Arpaio confirmed the arrest and said the star - who was jailed in 2009 on charges of drug possession, animal cruelty and theft, stemming from various arrests in 2008 - is now in a Phoenix jail where he is isolated from other inmates.

He added: "We would hope that he is finally sent to prison. We've arrested him five times already. How many times do you have to violate the law?"

The details of the 'Who We Be' rapper's arrest are unclear but it has been reported it is related to drug addiction.

DMX's lawyer Gary Jenkins said: "He's been battling addiction for some time and he's in need of treatment."

After the star's release in May 2009 he was sentenced to 18 months probation for verbally threatening a guard during his stint in prison.

Meanwhile, DMX's wife, Tashera Simmons, is planning to release a tell-all book about her life with the artist, called 'Strength of a Woman'.

A representative said: "She will be talking about her experience with her family and trying to hold them together through the DMX journey. Her story is a stellar, heart wrecking, powerful, firsthand account of survival and family strength in a chaotic life and the fame that came with that life."
