The man allegedly demanded sex from the elderly woman around 12:45 a.m. on Sunday on Greenwich Street in Lower Manhattan, WABC-TV reported.

When the woman refused, he reportedly attacked her — punching her face so many times her teeth fell out. The New York Police Department said the man also left the woman with a broken eye socket.
