Manos Ikonomidis, 20, died just after 4 a.m. Monday. Officers had responded to 16th Street near Seveth Avenue on reports of a man being assaulted, according to police.

The Brooklyn man was found unconscious and unresponsive with a stab wound to his chest and trauma to his body, police said. He was pronounced dead at the hospital.

Christopher Membreno, 24, of Brooklyn, was arrested Tuesday in the case. He faces a charge of murder and criminal possession of a weapon, NYPD said.

Investigators believe Ikonomidis was killed after a woman who participated in a threesome became enraged at one of the participants for filming the act.

Once home, in Staten Island, the the woman allegedly told her boyfriend, who was not involved in the threesome, that she had been raped, the Daily News reports.

So far, no evidence has been found to show the threesome was not consensual, police sources told the Daily News.

Ikonomidis’ girlfriend, who was also not involved in the sex act, later reportedly received a message on Instagram saying, “your boyfriend f—-d up and will be taken care of.”

Police believe friends of the woman involved sought revenge on her behalf, and killed Ikonomidis.
