TMZ Sports has obtained new footage of Gervonta Davis' attack on his ex-girlfriend ... and it appears to show the boxing superstar taking a swing at the woman.
As we previously reported, Davis was arrested last month ... after a woman told cops she was roughed up by the 25-year-old at a celeb basketball event on Feb. 1 in Coral Gables, FL.
Now, we've obtained new footage from the altercation ... and you can see, Davis CLEARLY gets violent with the woman.
Davis walks the baseline at the Watsco Center, immediately puts his hands on the woman's shoulder and neck area .
