The New York City Police Department was investigating Tuesday an apparent homicide in Manhattan.
Police say officers were called to an apartment located at 170 East 110th Street in East Harlem on Monday afternoon.
When they arrived, police found a man in his 40s with several stab wounds to his back and neck.
Sources say there was also a sheet around the man's neck.
They also say the man may be transgendered.
Neighbors told investigators that people came in and out of the apartment on a regular basis, and police are looking into whether there was prostitution going on.
As of Tuesday night, no arrests had been made.
Anyone with information about the case is being asked to contact Crime Stoppers by calling 1-800-577-TIPS, by texting TIP577 to CRIMES, or by going to NYPDCrimeStoppers.com.
