Jabari Bird allegedly strangled a woman at least a dozen times over a four-hour period.
The victim told police that Bird strangled her and threw her against a wall after they got into an argument at Bird's residence. She said Bird would strangle her until she went "limp," allow her to catch her breath and begin choking her again.
She also said that Bird kicked her multiple times in the stomach and dragged her away from the door when she tried to leave before shutting her into a bathroom.
Bird was charged with assault and battery with a dangerous weapon, assault and battery of a family or household member, kidnapping and strangulation following his arrest over the weekend.
Bird has entered a not guilty plea.
The Celtics drafted Bird with the 56th pick in the 2017 draft.
