A 35-year-old Springfield man has been accused of recording young boys as they performed sex acts during online video chats, authorities said.

Andrew Choi, 35, was arrested Friday and charged with production of child pornography, according to the U.S. Attorney’s Office in Virginia.

Choi took part in the video chats with the boys between May 2012 and January, federal authorities said. They said hundreds more pornographic images were found on Choi’s computer.
