Prosecutors declined to file charges against Sacramento Kings center Justin Williams on Tuesday over allegations that he sexually assaulted a woman.
Their decision was based on a report by Sacramento police investigators, who found there was not enough evidence to support criminal charges.
In a statement, the Sacramento County district attorney's office said it agreed with police but declined comment further.
Prosecutors said releasing more information would harm Williams, the woman who said she was sexually assaulted and another woman who also was in the home at the time.
"Based on the facts, statements and evidence, detectives cannot prove or disprove the allegations in this case," the police department said in a statement.
The department said it supports the prosecutors' decision not to file charges.
Williams' attorney, William Portanova, said the player and his girlfriend had consensual sex with the woman.
Portanova thanked both the police and prosecutors for a thorough investigation.
"We know that their work is all about finding the truth. That's all we wanted in this case," he said in a telephone interview. "They looked around every corner, and so did we."
Portanova said he expects Williams to quickly rejoin the Kings, whose next game was yesterday against Minnesota.
Kings spokesman Troy Hanson said the team would not have a comment until it was notified of the decision by the district attorney's office. Williams currently is on a leave of absence from the team.
