WNBA All-Star Riquna Williams has been suspended 10 games without pay following a domestic violence incident with her ex-GF back in December ... the league announced on Tuesday.
The story behind the arrest is crazy -- Williams allegedly showed up at her ex's Florida home, destroyed her car with a skateboard, forced her way into house, hit her in the head several times and pulled her hair out.
The 29-year-old is also accused of getting a firearm out of her car and pointing it at her ex's friend ... saying "you'll get all 18" before leaving the home.
