SEATTLE -- Shawn Kemp, a former Seattle SuperSonics power forward, was jailed Monday after officers stopped a pickup truck he was in and found what appeared to be marijuana and cocaine, authorities said.

King County Jail spokesman Capt. Troy Bacon said Kemp was being held for investigation of drug possession.

Without naming Kemp, the King County Sheriff's Office released a statement saying the arrest happened around 1 a.m. in Shoreline, a suburb north of Seattle, after an officer smelled a strong odor of marijuana while talking to two men in a parked Chevrolet pickup.

After searching the truck, the officer found what appeared to be a small amount of cocaine, about 60 grams of marijuana and a semiautomatic pistol, the sheriff's office said.

A law enforcement source told The Associated Press that one of the two 35-year-old men arrested was Kemp, who was scheduled to make his first court appearance Tuesday afternoon in county District Court.

Kemp, a five-time All-Star, was drafted by the Sonics in 1989 and played for Seattle until 1997, when he was traded to Cleveland in a three-way deal that brought Vin Baker to Seattle from Milwaukee.

Kemp also played for Portland and Orlando before ending his career in 2003.

He appeared in 78 NBA playoff games, leading the Sonics with 23.3 points and 10 rebounds per game in the 1996 finals against the Chicago Bulls.
