Security was stepped up at West Point after a possible terror threat that "may have been directed" at the military academy.

The West Point Garrison, which runs the academy's military police, released a statement on Facebook Sunday, warning visitors of a possible safety threat and increased security measures as a result.

The online release said the military and law enforcement were working to determine the credibility of the threat and that visitors should expect longer wait times due to more thorough vehicle searches at gates.

A representative for the military academy, which has thousands of cadets, said Tuesday that they were unaware of any threat, despite the social media post. The representative would not discuss security measures.

However, West Point Garrison officials say an investigation into the credibility of the threat is underway.
