Police Arrest Suspect In Fatal Park Slope Threesome Stabbing

PARK SLOPE, BROOKLYN — Police have arrested a man they suspect stabbed and beat a man to death in Park Slope after a threesome went awry.

Christopher Membreno, 24, was arrested and charged with the murder of Manos Ikonomidis, 20, in the lobby of 355 16th St., near Seventh Avenue, just before 4 a.m., police said.

Ikonomidis had been involved in a threesome in the Park Slope apartment building that came to a halt when he tried to videotape the encounter and a woman stormed out, the New York Post reported.

The woman then called Membrano, her boyfriend, who arrived at the Park Slope residence with two friends, baseball bats and knives, the Post reported.

The three men jumped Ikonomidis, beat him with the bats and stabbed him multiple times, police said.

Ikonomidis was found unconscious in the lobby and was transported to Methodist Hospital where he died, police said.

Police have yet to arrest the two remaining suspects, police said.
