The man, who lives in the city’s Queens borough but was not otherwise identified, was arrested on Thursday afternoon, the person said. He is expected to appear in U.S. District Court in Brooklyn later on Friday, but it was unclear what charges he would face.
The New York Police Department declined to comment on the matter and referred inquires to the Federal Bureau of Investigation, which also declined to comment.
The alleged plot was uncovered after police and federal authorities learned he was inquiring about buying grenades and using them in Times Square, one of the most visited destinations in the United States, the New York Daily News reported.
Authorities do not believe the man had links to a wider plot involving other people, the Daily News said, citing unidentified law enforcement sources.
Members of the New York Joint Terrorism Task Force, which is made up of FBI agents and New York police detectives, made the arrest. The task force began tracking him and eventually took him into custody, according to media reports said.
