BULLITT COUNTY, Ky. (WHAS11) -- There were a few scary moments for some North Bullitt High School students when another boy was seen carrying what appeared to be a gun Monday morning.
Authorities say the high school sophomore frightened other students when he carried pieces of a broken air gun in his waistband.
Another student, who saw the gun, told the bus driver, who called deputies. They pulled the bus over and arrested the student.
Deputies say the gun appeared, from a distance, to be real.
"You can look at the handle alone compared to my weapon. That's why it can appear to be a normal weapon," Lt. Mike Murdoch said.
The scare came on the first day of school after students learned of the massacre at Sandy Hook Elementary School in Newtown, Conn. in which 26 people, mostly young children, were fatally shot.
North Bullitt Principal Jeffrey Marshall says he immediately made an announcement about the incident and sent e-mails and letters to parents.
"They want to be reassured by adults," Marshall said. "Part of my job today was to make sure they're reassured and make sure we're doing the things we know to do to keep this a safe environment."
"Tensions are high because of what happened on Friday. Our sheriff has actually given a directive to our deputies to be in all the schools around the county," Lt. Murdoch said.
School officials are also paying close attention to rumors of potential violence circulating among social media.
"We brought in several students, talked to them asking if they'd heard anything about Facebook or Twitter. We never got a specific issue. It always led back to rumor and speculation," Marshall said.
Authorities say they're working to keep things as normal as possible, while keeping a close eye out for anything out of the ordinary.
"The unfortunate thing is you never can tell where it's gonna happen. We're gonna do the best we can. The school board's gonna do the best they can to make sure that every one of our students is protected," Murdoch said.
The student arrested faces charges of wanton endangerment, terroristic threatening and menacing.
