An electronics technician for the Federal Bureau of Investigation pleaded guilty on Monday to spying for China for five years, saying he did so in exchange for government-sponsored trips and prostitutes, the Justice Department announced.

Kun Shan Chun, who had worked in the FBI’s New York office since 1997, said he passed information to a Chinese official from 2011 to 2016. Chun, who immigrated to the United States in 1980 and became a citizen in 1985, held a top secret security clearance.
