Former Rikers Island Warden Says Brawl Could Impact Release Date

Diddy‘s recent prison fight could end up undoing some of the good behavior credit he’s already racked up … so says the former warden of Rikers Island.

Howard Robertson — a former New York City Department of Correction employee who rose to the top job at one of New York’s most notorious federal pens — joined us on “TMZ Live” Friday … and he told Charles everything Diddy does behind bars is being scrutinized, including the brawl.

Robertson says a judge will eventually look at his prison record and decide if he deserves credit for good behavior … and this violent fight could be a serious strike against him.

Diddy’s currently scheduled to get out of prison in February 2028 … but that date assumes he earns credits for good behavior.

Robertson says prison officials will investigate and figure out if Diddy was in the wrong in this cellblock showdown … and if so, he could be extending his stay in the federal pen.

Diddy wound up in solitary confinement after the fight … and Robertson explains why that is a good indicator on the status of the prison probe.

We also asked Robertson if Diddy would have been better off turning the other cheek here … but there’s some specific reasons he thinks that would have been the wrong move.

Diddy’s looked comfortable at Fort Dix every time we’d seen him before this … and it sounds like there’s a chance he may be extending his stay.
