Former UNC assistant research professor Kuo Hsiung Yang, 33, has been indicted on federal child pornography charges Tuesday, according to WRAL.

Yang was arrested in November and charged with 10 felony counts of second-degree sexual exploitation with a minor.

He was employed at UNC at the time of his arrest but the school said that he is no longer a member of the faculty, according to WRAL.

The FBI had been investigating Yang for duplicating videos of young girls being sexually assaulted, according to police reports.
