According to police, it happened during his son's birthday party at his home in Williamsburg. There were about ten 12-year-old boys there.
The incident was reported to Social Services a few days later by some of the mothers whose sons were at the party.
Police say after interviews with the kids and their families and conferring with the Commonwealth Attorney’s Office, charges were filed.
He was arrested Monday and charged with four counts of brandishing a firearm, which is a misdemeanor.
According to a university spokesperson, deCamp works in the mathematics department.
A 2005 article on the university's website goes into more detail about his military background, saying that deCamp was a lieutenant colonel in the Army and served in Iraq.
He was one of three soldiers involved in a 2003 incident in which two foreign journalists were killed. It happened when an American tank fired on a Baghdad hotel.
According to the article, after a review from the U.S. Army and U.S. Department of State, it was determined that the use of force was justified.
For the charges he is facing from the incident in May, police say deCamp was released on a summons. The man who answered the door at his house Wednesday said he had no comment.
