A member of the rap and fashion brand collective Slowbucks was reportedly beaten and robbed onstage while 50 Cent was performing with Fabolous at Hot 97's Summer Jam 2014 concert on Sunday (June 1).

As of now, there's no clear reason as to why the Slowbucks member was beaten, but back in April, rapper Trav posted an Instagram photo with Slow Buck and 50's son, Marquise Jackson, and the rapper apparently didn't take too well to it.

In addition, Slowbucks was recently signed to Epic Records by Sha Money XL -- Fif's former manager -- so the six degrees of separation is pretty close, but that didn't seem to slow down the altercation any.

In a newly released YouTube video, you can clearly see 50's entourage kick and punch somebody, and appear with a gold chain afterwards. There are also reports that Fab and others tried to calm the situation down.

So far, the only response comes from Slowbucks via an Instagram page. In the photo, the alleged victim poses in front of two Ferrari vehicles with a gold chain around his neck. "#HateMeNow on #iTunes right now! #SlowBucks #OverEverything aka #SBOE #Queens N%a," reads the caption. The 'Hate Me Now' he's referring to is the classic 1999 song from Nas featuring Diddy.

Either way, the melee puts another notch in 50's belt, in terms of his reputation as a rapper not to be messed with.

Below are Twitter reactions from two concertgoers who saw the attack happen right before their eyes.
