A Rikers Island inmate suspected of strangling another prisoner to death in July was charged with murder on Tuesday, police said.

Artemio Rosa, 27, allegedly came up behind another inmate while he was sitting in the Anna M. Kross Center and choked him to death on July 9, sources told The Post after the incident.

Correction officers pulled Rosa away from the 35-year-old victim, but he collapsed and died before medics could revive him.

“This loss of life is a tragedy, and serious violence of this nature is incredibly troubling,” Mayor Bill de Blasio spokeswoman Natalie Grybauskas said in a statement after the slaying.

Rosa has been arrested 36 times in the past decade and has bounced between homeless shelters and city jails, assaulting workers and causing mayhem in the facilities.

At a homeless shelter last May, Rosa allegedly attacked staff and other residents with a fire extinguisher, stabbed himself in the neck and threatened to blow up the building.

He assaulted correction officers four times in a month after being arrested June 7 for smashing a driver’s windshield and stealing a cellphone.
