The UK's Daily telegraph reported Tuesday that 56-year-old Haddad from Manhattan's Chelsea neighborhood made anti-Semitic threats against both the 87-year-old woman and a 78-year-old woman over a month-long period.
Police said that racist threats were left on a voicemail message, and that swastikas were also drawn on the women's apartment doors.
"He threatened to kill the other individual on the phone as well as her relatives," said a police spokesman. "He said basically that all Jews should die and go to hell."
Haddad, who was charged with aggravated harassment as a hate crime, was also accused of taping notes with anti-Semitic symbols including swastikas on five apartment doors and in the hallway of a building in the Chelsea neighborhood.
Swastikas were spray-painted on garage doors, some with the words "Die Jews", which police believe was part of Haddad's anti-Semitic spree.
