SACRAMENTO, Calif. -- Sacramento Kings backup forward Justin Williams has been named as a suspect in the investigation of an alleged sex assault that police say may have taken place at the player's Sacramento home.

Sgt. Matt Young, spokesman for the department, said Thursday that the alleged victim told investigators the attack took place early Friday.

Young added that Williams has been cooperative.

"He is a suspect in this investigation," Young said.

Kings spokesman Troy Hanson said Williams has been given an indefinite leave of absence and returned to Sacramento from a road trip to New Mexico to obtain a lawyer, a step recommended by team officials.

Hanson would not say whether the team planned to suspend Williams.

Officials said they found some evidence Wednesday while carrying out a search of Williams' home, but they did not say what they found. Williams has yet to face any charges.

The alleged victim was described a woman in her 20s who has known Williams for some time.

Young added that there was one other person present during the alleged attack, but that person's name was not released.

Young said police became aware of the allegations on Friday after the alleged victim went to a local hospital.

Williams, 23, is a center and power forward. The Kings picked him up last season as an undrafted rookie free agent out of the University of Wyoming.

Williams, who stands 6 feet 10 inches, played in just 26 games last season. Heading into his second season, he is playing under a nonguaranteed contract.
