*Former NBA star Isaiah “J.R.” Rider was arrested in Arizona on Tuesday for a probation violation and detained on a no-bail hold in a Maricopa County jail. But during his appearance in court, he was clueless as to what he did to get there. [Scroll down to watch.]

According to court documents obtained by TMZ, Rider violated his probation by failing to complete his probation requirements — which included 100 hours of community service, (he only did 10), completion of domestic violence classes, submitting to a urinalysis test and paying fines.

Rider’s probation officer said in court papers that Rider’s “failure to participate in treatment after so many opportunities appears to reinforce his lack of intent to successfully complete probation.”

Police also believe Rider is a flight risk and want to keep him behind bars, TMZ reports.  Rider is due back in court on Oct. 11.
