Prosecutors in Kent, Wash., said Wednesday that they need more time to investigate allegations against Celtics guard Terrence Williams before filing charges.

Williams, a Seattle native, is being investigated for second-degree domestic assault.

He was arrested Sunday after a parking lot confrontation in which the mother of his 10-year-old son told police that Williams threatened her with a gun.

Williams spent Sunday night in jail and posted a $25,000 bail Monday. He was scheduled to attend a court hearing Wednesday, the deadline for prosecutors to file charges.
