Memphis Grizzlies star Zach Randolph has been tied to drug charges after one of his friends was stopped in Indianapolis driving a truck owned by the NBA player that contained marijuana, the Associated Press reported.

According to the AP, court documents say Arthur Boyd, 32, was arrested on May 11 during a routine traffic stop after police discovered three ounces of marijuana in a cooler inside the Cadillac Escalade, which was registered in Randolph’s name.

Boyd, a longtime associate of Randolph, was arrested after police followed up a tip that Randolph was involved with Indianapolis-area drug dealers, according to the AP.

Randolph has not been arrested or charged with a crime in connection with Boydโ€™s arrest. Randolphโ€™s attorney, John Tompkins, told reporters on May 27 that his client denies any involvement with drug activity. According to Tompkins, the man arrested is a longtime friend who takes care of Randolphโ€™s home in Indianapolis.
