New York, June 18: Indian national Nikhil Gupta, suspected by the US of involvement in an unsuccessful plot to kill the India-designated pro-Khalistani terrorist Gurpatwant Singh Pannun on American soil pleaded not guilty on Monday (local time) at a federal court in the US.

Gupta arrived at the Manhattan Federal Courthouse in New York City at 12:30 PM (local time) and has pleaded not guilty in court. Gupta was extradited to the US from the Czech Republic on Friday. While speaking to reporters, Gupta's US-based lawyer, attorney Jeffrey Chabrowe said that they would file a bail application at a later date, meaning Gupta will continue to be detained for now. Gurpatwant Singh Pannun Murder Conspiracy: Indian National Nikhil Gupta Produced in US Court, Pleads Not Guilty in Murder for Hire Plot.

The New York-based attorney will be allowed to speak with Gupta again. The next hearing is on June 28.

Nikhil Gupta has been accused by US federal prosecutors of plotting with an Indian government official to kill Gurpatwant Singh Pannun. The discovery of alleged assassination plots against Pannun in the US has brought the India-US relationship under the spotlight. Gurpatwant Singh Pannun Murder Conspiracy: Indian National Nikhil Gupta, Accused in Alleged Plot To Kill Khalistani Terrorist, Extradited to US From Czech Republic.

New Delhi has firmly dissociated itself from the plot against Pannun, saying it is against the Indian government's policy. It has said it would formally investigate security concerns raised by Washington. The US Justice Department has alleged that Gupta (52) is an associate of the Indian government and that together they and others helped plot the assassination of Pannun in New York City.
