Rockets guard Rafer Alston was arrested early Sunday morning in downtown Houston on charges of assault and public intoxication, police said.
Both charges against Alston are misdemeanors, said Victor Senties, a Houston police spokesman.
"We are aware of the situation and are attempting to get more details about the incident," Rockets general manager Daryl Morey said in a statement. "While we do not have all the facts yet, it is nevertheless very disappointing to have one of our players involved with any police activity. We will continue working with the authorities in order to get to the bottom of the situation."
Senties had no information whether Alston had been jailed or if he had an attorney.
Alston joined the NBA during the 1999-2000 season with Milwaukee. He signed with the Rockets in 2004 and averaged 13.3 points last season.
