Two Penn State university officials who are accused of misleading a grand jury in its investigation into child sexual abuse allegations against a former assistant coach have stepped down, the university said early Monday morning.

Penn State Athletic Director Timothy Curley, 57, and Gary Schultz, 62, the university’s senior vice president for finance and business, face charges of one count of perjury each.

They stepped down late Sunday after an emergency meeting of the university’s board of trustees.

The man at the center of the case is former assistant football coach Jerry Sandusky, 67, who served 23 years as defensive coordinator for the Nittany Lions football team.

Penn State students are in ‘disbelief’ that Sandusky allegedly engaged in fondling, oral sex and anal sex with young boys over a period of more than 10 years, according to an investigative grand jury’s summary of testimony.
