SAN RAFAEL -- Troubled former pro basketball star Isaiah J.R. Rider was on the run Thursday after a Marin County judge issued two arrests warrants for him after he failed to show up for a sentencing hearing.

Marin Superior Court Judge Verna Adams waited for more than an hour Wednesday after Rider failed to show up for his 9:06 a.m. court appearance. The judge set a $10,000 bail for each of the warrants in two separate misdemeanor cases against the basketball player.

Rider had pleaded guilty to six misdemeanors and three infractions in the two cases in Marin. One for false imprisonment and battery. The second is for driving with a suspended license and related charges.

He also is wanted in Alameda County, where a bench warrant was issued July 26 when he failed to appear in court on drug charges.

Rider, 34, was arrested in January after an ex-girlfriend said he had forced her into his Mercedes-Benz and refused to release her.

The former Portland Trail Blazer star allegedly got into an argument with the ex-girlfriend the night of Wednesday, January 25, and drove off with her against her will, according to Sgt. Bruce Baker of the Marin County Sheriff's office.

The woman began to scream, attracting the attention of police. Authorities tracked Rider down early the following morning and arrested him, Baker said. The woman was not injured.

Rider racked up hundreds of thousands of dollars in fines and suspensions in his NBA career, which ended in 2001. His offenses ranged from being tardy to practice to spitting at fans and airport personnel to crimes of assault and marijuana possession.

He spent two days in jail for failing to perform court-ordered community service for a 1994 assault charge -- kicking a woman in the back after a disagreement at an autograph signing.

In May 1997 he was convicted of marijuana possession and later pleaded no contest to possessing unregistered cellular phones.

Rider was the fifth overall pick by Minnesota in the 1993 NBA draft and spent three seasons with the Timberwolves, winning the slam dunk championship his rookie season.

He was then traded to Portland in 1996 and spent three seasons with the Trail Blazers. He was suspended for a total of 12 games during his time in Portland, including three by the NBA in 1997 for spitting at a fan in Detroit.

After getting traded to Atlanta for Steve Smith on Aug. 2, 1999, Rider was late to his first day of camp, and never could get along with coach Lenny Wilkens. He was released in March 2000 after refusing to accept a three-game suspension for being late to a game.

He spent the 2000-01 season with the Los Angeles Lakers and was suspended five games that season for violating the league's anti-drug program.

He joined Denver the next season and was waived in November 2001 after playing just 10 games with the Nuggets. Rider never played again in the NBA.

Rider averaged 16.8 points per game in his career.
