has reportedly been put on "lockdown" in Arizona's Tent City Jail after threatening guards.
In January, the star, real name Earl Simmons, was jailed for three months for theft, drug possession and animal cruelty. TMZ.com reports the rapper failed to report for his medication and threatened to "assault somebody to get some respect."
His actions prompted prison officials to place DMX on lockdown and punish him with a "special diet."
