An Indian man the U.S. suspects was involved in an unsuccessful Indian government-backed plot to kill a Sikh separatist on American soil pleaded not guilty on Monday to murder-for-hire conspiracy charges in federal court in Manhattan.
U.S. federal prosecutors accused Nikhil Gupta of plotting with an Indian government official to kill Gurpatwant Singh Pannun, a U.S. resident who advocated for a sovereign Sikh state in northern India.
Last June, Gupta traveled to Prague from India and was arrested by Czech authorities.
