Students and staff in Orono public schools raced to barricade doors with desks, metal cabinets and chains Wednesday after social media posts threatened a school shooting.
Outside the four-school campus, snowplows and police cars blocked access to roads leading to the schools. Parents sat in long lines of cars, texting with their children who were locked down inside.
Police were notified at 10:57 a.m. of threats on Twitter and Facebook that a shooting would happen at noon, Police Chief Correy Farniok said after the lockdown was lifted.
A male student was arrested about 4:15 p.m. pending felony charges of terroristic threats, Farniok said. A second male student is a "person of interest," the chief said, but has not been arrested.
In the morning, a screenshot of the threat on Twitter made the rounds at school.
"Orono is not safe. Today at 12:00pm I will shoot up the school myself," the tweet said, coming from a handle called "Anonymous Vector."
Police determined that both threats originated from the high school, the chief said. The suspects were identified and both boys were found inside a classroom. Neither was armed and no guns have been found, the chief said.
"We haven't found anything, but the investigation is ongoing," Farniok said.
