The naked body of a young woman was found stuffed in a green duffel bag and dumped on a sidewalk in Manhattan, according to police and sources.

MTA Police were called to 125th and Park Ave. in East Harlem shortly before 7 p.m. on Monday after a passerby made the grisly find underneath the Metro-North railway.

The body was described as that of a white female in her 20s, inside of a black garbage bag, which was then left in a green duffle bag secured by a drawstring and dumped on the sidewalk, sources told The Post.

No trauma was visible on the body and no cause of death has yet been given.

The woman is yet to be identified as police await a full medical examiner’s report.
