The criminal complaint charges Hasanzadeh with interstate transportation of stolen property and fraud and misuse of visas, permits, and other documents. It was alleged that in or about January 2015 and in or about June 2016 Hasanzadeh knowingly and willfully stole confidential documents and technical data for his employer and thereafter emailed those documents to multiple individuals including his brother Sina Hasanzadeh in Iran.
