Pennsylvania State Police Academy cadets have left the facility either because they have been dismissed or have decided to resign amidst an investigation on allegations of cheating within the student troopers.

Tyree Blocker, a commissioner of the academy, has declined to reveal other details of the allegations on its 144th graduating class, other than the fact that the investigation was prompted when an academy staff found out that the testing process could have been compromised.

"We're working very diligently at bringing some closure to the investigation. However, I want to be clear. We will not leave any stone unturned when it comes to the integrity of the Pennsylvania State Police," Blocker said in a statement, according to Fox News.

An uncited police source reported that a "cheat sheet" had been discovered, according to Penn Live. The sheets could have been acquired and circulated when some test materials were not changed between classes, and this is also something that the academy has vowed to look into.

The investigation on the allegations is still ongoing.

"We won't tolerate anyone who lies, cheats or steals. The public has, and rightfully so, an expectation that members of the State Police have the highest integrity and I am insistent on that," Blocker said, according to The Washington Post.

Pennsylvania State Police is one of the nation's largest law enforcement agencies. Amidst the issue and of the 29 cadets leaving, 69 remaining cadets are scheduled to graduate mid-March.
