A Boston University graduate student who has been linked to an elaborate cheating scandal at Purdue University in Indiana is no longer enrolled at BU, a school official said.

BU spokesman Colin Riley said Wednesday that Roy Chaoran Sun of Andover, who is charged with breaking into professors' university accounts to inflate his grades, has left Boston University. Riley would not elaborate, but he confirmed that Sun was enrolled in a BU graduate program for one semester.

According to the Lafayette Journal & Courier, in April, the Tippecanoe County prosecutor’s office charged Sun, 24, as well as Mitsutoshi Shirasaki, 24, and Sujay Sharma, 24, with several felonies and misdemeanors, including conspiracy to commit burglary, conspiracy to commit computer tampering, and conspiracy to commit computer trespass.

The court documents were unsealed and made public last week.

According to the affidavit, Sun and Shirasaki changed their grades by breaking into professors’ offices and classrooms, and installing keylogging software. From this, Sun and Shiraski were able to figure out their professors’ log-in information, and hack into their accounts to inflate the grades.

The affidavit said that Sun changed eight F’s and one D to straight A’s. Shirasaki allegedly boosted his grades from F’s D’s and C’s to B’s and A’s, and switched one A to an A+. Shiraski is also being accused of changing a grade for his girlfriend, from an A to an A+.

The affidavit said that Shirasaki gave Sharma a few exams downloaded from a professor’s computer, and helped him change a grade from a D to an A. Sharma also allegedly acted as a lookout for Shirasaki.

John Cox, the chief for the Purdue University Police Department, told the Purdue Exponent that he has never had to deal with a case like this before.

“This was no outside attack,” Cox said. “This was [done by] some students who were very smart and used their knowledge and wisdom to do something they shouldn’t have.”
