Ryan Hemphill is accused of raping six women over five months in a depraved rampage. Prosecutors believe there are more victims.

Manhattan authorities said an attorney raped, assaulted and methodically humiliated six women over five months in his Midtown apartment — at times using shock collars and electric cattle prods to torture them and recording the abuse with cameras throughout his home.

A New York City private equity executive beat and tortured several women in his apartment over a five-month period, prosecutors said in court Thursday.
