Police are looking for a man who they say grabbed a Brooklyn woman from behind and nearly raped her — all while wearing no clothes.

The woman was heading toward her home near East 55th Street and Avenue J in Flatlands just after 11 p.m. Monday when she was attacked, according to authorities. That’s when the suspect approached her from behind, grabbed her by the neck, threw her to the ground and forcibly touched her, police said.

The nude suspect fled the scene after the victim was able to free herself, according to police.

Authorities describe the suspect as about 25 to 30 years old with a thin build.

Anyone with information in regards to this incident is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477). The public can also submit their tips by logging onto the Crime Stoppers website or by texting their tips to 274637 (CRIMES) then enter TIP577. All calls are strictly confidential.
