A college student in Florida is facing serious charges after allegedly having 1,500 rounds of ammunition delivered to his dormitory, along with a semi-automatic rifle found concealed under his bed, as reported by law enforcement officials.

Constantine Demetriades, a senior at Rollins College, was taken into custody by Winter Park police on Wednesday. The 21-year-old has been charged with possessing a weapon on school premises. This arrest came after the college’s assistant campus safety director reported the ammunition order to police, according to an arrest affidavit cited by WKMG.

Upon flagging the ammunition purchase, the assistant safety director conducted a search of Demetriades’ dorm room. During this search, authorities allegedly found an unloaded AR-15 rifle stored under the bed in an unsecured black carrying case. Accompanying the rifle was one loaded magazine, five empty magazines, a tactical vest, knives, a black security vest, and ear protection.

Demetriades, who enjoys shooting as a pastime, explained to police that he had the firearm on campus because he had recently returned from a Thanksgiving trip to New Jersey. He claimed that the weapons were legally purchased and registered there, according to the affidavit.

Demetriades, who said he likes to shoot as a hobby, told police he had the rifle on school property because he had recently returned from a Thanksgiving trip to New Jersey, where he said the guns were purchased and registered legally, according to the affidavit.

He said he did not have ill intentions and that he usually stores the firearm at a friend’s home off school property, the affidavit stated. He also said he only brought the gun to campus on one other occasion.

While Florida allows open carry, Rollins College bans all weapons on campus. Demetriades allegedly said he is aware that weapons are not allowed on campus and that his New Jersey concealed carry permit does not apply in Florida.

The college told WKMG that he is banned from campus until the situation is resolved, adding that an internal investigation has been opened.
