Coolio Gets Bench Slapped by Judge

For the first time since 1995, Coolio is a wanted man again.

TMZ has learned a $10,000 bench warrant was issued for Coolio's arrest today, after the rapper failed to show up to court in L.A for a progress report hearing.

Court documents show Coolio's lawyer tried to get in touch with the rapper to find out why he was a no-show ... but couldn't get him on the horn.

Coolio has been on probation since last year, after pleading guilty to possession of a controlled substance -- specifically, crack cocaine at LAX.
