KIPS BAY, NY — A vandal has drawn swastikas and male genitals on more than a dozen apartment doors in Manhattan in the last 30 days, police said on Wednesday.

Officers are searching for a man who is suspected of vandalizing apartment buildings throughout Manhattan with swastikas and male genitals. Police have not yet identified the suspect, but released a photo on Wednesday of the man they believe has spray-painted the hateful images. The police department's hate crimes task force is investigation the incidents. Police say the vandalism began on Nov. 26, when the man entered a Kips Bay high-rise near Madison Avenue and East 29th Street. At about 7:30 p.m. that night, the man went to the 48th floor of the building and drew two swastikas on apartment doors, male genitals on a third and "Max G was here" on the fourth door, according to police.

Just a few days later, the man went inside a Financial District apartment building near Pine Street on Dec. 2 at about 3 p.m. Once inside, police say the man drew an upside-down cross on the building's elevator doors, before drawing multiple swastikas and male genitals on other apartment doors, in addition to the tag "Max G was here." On Dec. 18, the man entered an apartment building near North Moore and Greenwich streets and drew a swastika, male genitals and "Max G was here" on two different floors in the building, according to police. The next day, authorities say the man went inside a Chelsea apartment building, located on W. 29th St., at about 11 p.m. and drew swastikas on three different doors before drawing male genitals on six additional apartment doors.
