TERRE HAUTE, Ind. (WTHI) - Vigo County students are back at home with their loved ones.
This comes after Terre Haute Police investigate a threat at a Terre Haute high school.
News 10 has learned the suspect police believe is responsible for a threat at Terre Haute North Vigo High School remains at large.
It all started just before 11:00 Friday morning.
Police responded to reports of someone with an AR-15 and explosives at the school.
Vigo County School Corporation leaders immediately placed the school under a `code red.`
Students were evacuated to the gym.
That is when police sent in around 50 officers, including K-9s to search for any bombs.
After searching each classroom, police found no evidence that the threats were true.
The students were later released into their parent`s custody.
The Terre Haute Police Department and the Vigo County School Corporation held a joint press conference Friday afternoon at the Vigo County School Corporation building.
Superintendent Danny Tanoos and North Principal Robin Smith say protocol was followed when the threat was made.
Now, the search is on for who made the threat.
Police Chief John Plasse said his desk officer took the initial call from the suspect, who was then transferred to Central Dispatch.
The suspect told the dispatcher he was inside a restroom with the AR-15 and explosives, and he wanted a ransom paid, or he was going to detonate the bombs.
Plasse said at the end of the day, they found no evidence of explosives or a weapon at the school.
"I would like to ask the community that if you think you know a tip that might be significant or even insignificant to call Crime Stoppers at 812-238-STOP. Call the police because we want this individual taken into custody as soon as possible," Chief Plasse said.
After school activitis proceeded as normal.
Tanoos said there would be school on Monday, though he anticipates throwing additional resources to the school, including a few extra officers just to help everyone feel safer.
