A University of Waterloo student is under scrutiny after an alleged spying incident at U.S. airports, with authorities tying the case to photographs of aircraft at Chicago O’Hare International Airport. The FBI described the episode as captured on security video on April 21, when an unidentified man was seen taking pictures of planes, an activity later connected to the Waterloo student, Weiheng Zeng, according to a criminal complaint. The report details a pattern of behavior linked to Zeng, who was identified in relation to the O’Hare footage. The investigation centers on whether the actions constituted espionage or other wrongdoing, though specific charges or outcomes were not provided in the material. The events have drawn attention to a university community in Ontario and to the broader issue of security at major transportation hubs. Authorities have not released additional information about motives, potential targets beyond the photographed aircraft, or any subsequent steps in the legal process. The case underscores ongoing concerns about individuals who collect or transmit information about critical infrastructure, particularly in the context of international scrutiny.
