Sexual Assault Charged Dropped Against NIU Officer
Description:Former Northern Illinois University police officer Andrew Rifkin is no longer charged with sexually assaulting an NIU student.
A DeKalb County judge ordered the charges against Rifkin dropped because the police department may have withheld evidence the sex was consensual.
A campus computer specialist testified, NIU Police Chief Donald Grady ordered him to remove dozens of files from the chief's computer.
It's not clear whether those files were from the Rifkin investigation.(0:26)
