HYDE PARK, OH (FOX19) - A teen was arrested at Withrow High School after several 911 calls were made that Cincinnati police determined to all be hoaxes.
The school was on lockdown for about two hours Thursday morning.
Nine calls were made between 9:12 a.m. and 9:44 a.m., prompting teams of police and one from Cincinnati Public Schools to respond to the Madison Road school, police said in a prepared statement.
In one of the calls, laughter could be heard in the background, according to police.
A 13-year-old female student from Withrow has been arrested and charged with felony inducing panic.
Investigators are still in the process of identifying the other callers.
One of the calls reported a teacher assault, police said earlier this morning, adding that it didn't seem credible.
Worley confirmed it was an untrue report.
The building was searched, but nothing was found to indicate any of the calls were true, police said. The lockdown was lifted about 11 a.m.
"Everyone was, like, so scared," said Aleyah Wilson, a student. "Everybody was crying. It was just a lot to handle. They told us to stay put and be quiet."
Police now consider the incident a criminal investigation and turned it over to the Youth Services Section.
"This behavior is very serious We don't take it very lightly. The school don't take it lightly," Assistant Police Chief Dave Bailey told reporters on scene, according to a video clip posted to the police department's Twitter account. "We are still investigating it. I can't talk about that right now because we are only a few minutes into it. They are doing some interviews now. I am fairly confident we are going to have some resolution this afternoon ... people can get hurt by this behavior. We're not going to take this lightly."
Police said this is an ongoing investigation with additional arrests anticipated.
"It is absolutely the kind of thing one could get expelled for," said CPS Chief Communications Officer Lauren Worley, who watched on location at the school, as police searched every inch of the building.
Anyone with information regarding the calls is encouraged to call District 2 at 979-4400 or Crime Stoppers: 513-352-3040.
