The man who got socked in the face by NBA star Jahlil Okafor says Jahlil is lying about being heckled ... and got violent because he was mad he got rejected by two chicks on the streets of Boston.
The Boston PD says the victim filed a police report Friday morning, claiming Okafor hit him so square in the face, he sustained a cut above his eye that required stitches.
The victim also says Okafor's allegations that he was swarmed by hecklers outside of Storyville nightclub is pure garbage.
The truth, according to the victim, is that Okafor approached two girls that were hanging with the victim and tried to get their numbers. The girls weren't interested, and shot Okafor down.
The victim claims a verbal altercation ensued ... and Okafor became unhinged, eventually rushing at him and punching him in the face ... as you can see in the video first posted by TMZ Sports.
The Boston PD says detectives are "actively investigating the incident" ... but so far no charges have been filed.
As for Okafor, he says he's embarrassed by the incident, but stands by his story that he reacted because he felt threatened by hecklers.
