Otterbein University took part in disaster drills on Tuesday. The university says the threat was not part of the drills.

Otterbein University was one of three locations in Franklin County taking part in mass casualty drills, Tuesday.

The school had tweeted a message to students, assuring it was only a drill.

#Otterbein is taking part in an emergency disaster drill that is Franklin County wide. THIS IS ONLY A DRILL. THERE IS NO EMERGENCY. https://t.co/acPxBu9KFz — Otterbein University (@Otterbein) April 4, 2017

But, then, another tweet was sent out.

Otterbein Alert: Suspected bombn threat in area near Science Center. Clear the area until further notice. — Otterbein University (@Otterbein) April 4, 2017

"I was confused if the alert is serious or is this just a part of the drill," Samantha Devkota said.

"It definitely sends panic," Nick Tholt said. "I was actually at the end of class, today, when I looked at my phone and I saw that there was the alert of the bomb threat in the Science building."

Students, at first, were wondering if the bomb threat message was a part of the drill. For some students, it created confusion.

It was not confusing for Tara Chinn because the school's environmental health and safety officer had been planning the drill for the past six months.

"When they said that there was a bomb threat at the Science building, I immediately knew it wasn't part of the drill," she said.

From that moment the drill was over. Fire and police crews responded to the Science building.

"They were blocking the streets to cross even the roads and I was like 'I don't know what's happening'," Devkota said.

Crews conducted a thorough search before finding nothing and giving the all clear. The school sent out another tweet.

#Otterbein Alert: ALL CLEAR has been issued regarding threat at the Sci Center. Classes have resumed. This WAS NOT part of the drill today. — Otterbein University (@Otterbein) April 4, 2017





Tholt said it was handled well by first responders, however it was all bad-timing due to the day's drills.

"Expecting a drill and then when you receive a text like that, a message like that, you don't really know what to think," he said.
