Prior to joining McDermott, Sagar was a federal prosecutor at the US Attorney’s Office for the Southern District of New York (SDNY), where he served most recently as chief of the Complex Frauds and Cybercrime Unit. In that leadership role, Sagar oversaw approximately 20 senior prosecutors responsible for investigating and prosecuting some of the most sophisticated fraud and cyber cases in the country, many of which were international in scope. He also supervised some of the first US criminal investigations involving AI.

As a prosecutor, Sagar led and supervised cases and cross-border investigations involving the Foreign Corrupt Practices Act (FCPA), the False Claims Act (FCA), healthcare fraud, securities and investment fraud, intellectual property and trade secrets theft, tax offenses, and money laundering and the Bank Secrecy Act (BSA). During his time at SDNY, Sagar tried and supervised 23 federal criminal trials to verdict and handled 10 appeals before the US Court of Appeals for the Second Circuit. In addition to the DOJ, through his extensive experience with joint and parallel investigations, Sagar has had regular engagement with multiple civil regulators, including the US Securities and Exchange Commission, the US Commodity Futures Trading Commission and the Federal Trade Commission, among others.

Recognized for his experience handling novel, high-profile criminal cyber and national security cyber cases, Sagar provides clients with strategic counsel during interactions with US and international law enforcement agencies and regulators in sensitive cyber matters. He counsels clients on handling complex cross-border cybersecurity and data breach incidents, ransomware attacks and cybersecurity issues related to AI. Sagar also advises clients on the full spectrum of digital asset matters, including cryptocurrency theft and investment fraud, the manipulation of smart contracts, fraud in non-fungible token (NFT) offerings and the use of cryptocurrency to launder crime proceeds.

Before he joined SDNY, Sagar clerked for the Honorable Kiyo A. Matsumoto of the US District Court for the Eastern District of New York. He began his legal career at another international law firm representing corporate and individual clients in a variety of white-collar matters.
