Sixers' Okafor swings at another heckler in new video of Boston street fight

A second video has emerged detailing an incident between Philadelphia 76ers center Jahlil Okafor and a group of hecklers in Boston.

TMZ Sports has obtained footage (warning: explicit) that appears to show Okafor challenge a heckler to a street fight, before the fracas grew larger. That heckler had followed the 6-foot-11 rookie down the street, but it was Okafor that threw the first punch.

That same heckler was later pictured passed out on the concrete and bleeding from his temple, although the video doesn't necessarily show who injured him.

An earlier video showed Okafor engaging a second heckler in a separate incident on what appeared to be the same night.

Boston police have launched an investigation into the incident and officials told TMZ that charges will likely be filed.

In the meantime, the Sixers have reportedly agreed to have a security guard accompany Okafor.
