According to a press release, at approximately 4:27 a.m., officials received a report of a burglar alarm from the school.
Upon arrival, deputies discovered an alleged suspicious vehicle in the parking lot.
Deputies were met by a school official and determined the alarm was coming from the concession stand, which is located between the school's football and baseball fields on the north side of the facility.
As the school official was explaining to deputies which alarm had been activated, they spotted a male in a blue shirt near the concession stand.
Deputies entered the fenced area surrounding the playing fields and apprehended two male suspects without incident.
One of the suspects was later identified as Emmanual Sanders, 22, Cloverdale. The other suspect was a 17-year-old juvenile from the Putnam County area.
The deputies checked the concession stand area and found the entry door was forced open. They also noted fresh pry marks were evident on the door frame.
They then saw glass doors on two coolers inside the concession stand had been shattered and discovered the letters "GHS" sprayed inside the concession stand using Reddi-Whip whipped cream.
Deputies also linked the two suspects to the suspicious vehicle they had witnessed in the parking lot. As the deputies prepared to have the vehicle towed, they discovered property that appeared to belong to Greencastle High School inside.
Officials with the Greencastle Police Department were called, and they called the Putnam County school, finding out that two buildings on the school property had also been burglarized.
Both suspects were arrested on preliminary charges of Burglary (a Class C felony), Possession of Stolen Property (a Class D felony), Criminal Trespass on School Property (a Class D felony) and Criminal Mischief (a Class A misdemeanor).
Sanders is currently held in the Clay County Justice Center on a $10,000, cash only bond.
The arrested juvenile was transferred to a juvenile detention facility pending his initial hearing.
The two could face additional charges in Putnam County.
