In a significant development that has sparked international tension, Nikhil Gupta, a 53-year-old Indian national, was arrested at Prague's Vaclav Havel Airport in connection with an alleged plot by Indian intelligence to assassinate Sikh separatists in Canada and the United States [1][2][3][4][5].

The arrest, carried out by Czech authorities on June 30, 2025, was the result of a coordinated effort involving U.S. law enforcement agencies. Two officers from a U.S. task force, including a Drug Enforcement Administration special agent and a New York City Police Department detective, were present in Prague for the operation [1][2][3][4][5].

According to sources, U.S. officials had provided detailed information to Czech authorities about Gupta's arrival. The suspect, also known as Nick, was apprehended after collecting his luggage, with international paperwork for his arrest and extradition to New York already in place [1][2][3][4][5].

The case has been described as 'extraordinary' and 'politically sensitive,' highlighting the complex nature of the alleged conspiracy. The involvement of Indian intelligence in a plot targeting Sikh separatists on North American soil has led to significant diplomatic fallout between India, Canada, and the United States [1][2][3][4][5].

The operation leading to Gupta's arrest involved extensive undercover work by U.S. and Czech authorities. Details of the investigation reveal a sophisticated international effort to uncover and prevent the alleged assassination plot [1][2][3][4][5].

As Gupta faces extradition to the United States, legal battles are expected to unfold in U.S. courts. The case raises critical questions about international law, diplomatic relations, and the rights of diaspora communities [1][2][3][4][5].

This incident has strained relations between the involved countries, with Canada and the U.S. expressing serious concerns over the alleged involvement of Indian intelligence in extraterritorial assassination attempts. The diplomatic repercussions are likely to be far-reaching and long-lasting [1][2][3][4][5].

As the story continues to develop, international observers are closely watching the legal proceedings and diplomatic negotiations that will shape the outcome of this unprecedented case [1][2][3][4][5].
