Former NBA star Zach Randolph is currently at the center of a police investigation ... after cops say a woman told them he roughed her up during a 2024 incident.
Law enforcement sources tell TMZ Sports ... the woman alleged the attack went down in September -- after the two had gotten into an argument at a Los Angeles-area home.
It's not yet clear why the woman waited multiple months to report the claims -- though we're told she did present authorities with photographs of the injuries she said she suffered at the hands of Randolph.
