The Mount View Complex in Thorndike was evacuated Wednesday and police the following day announced a 16-year-old female was charged with disorderly conduct and criminal use of disabling chemicals.

School Resource Officer Jordan Tozier, a Waldo County sheriff's deputy, on Wednesday received information that the source of the chemical odor/release at the high school may have been an over-the-counter pepper-spray product, which was later confirmed.

Students and staff evacuated the building and remained at the complex while emergency responders attempted to identify the substance. Waldo County Sheriff's Office confirmed that pepper-spray was released in a classroom at around 2:20 p.m Feb. 28. The over-the-counter product is often used for self-defense, police said, but the circumstances that lead to its discharge at the high school have not been released.

The fire department subsequently cleared the building and found no other hazardous vapors or fumes present. Meanwhile, parents in cars and school buses waited to pick up students until after the area was cleared.

Once the source of the chemical release was identified and the building was cleared by hazardous material personnel, students and staff were allowed to leave the complex.

Responding to the scene were Maine State Police troopers, Waldo County Sheriff's Office, Unity Ambulance, Freedom Fire Department, Liberty Fire and Rescue, Montville Fire Department, Thorndike Fire Department and the Waldo County Mobile Command and Hazmat Unit.

No injuries were reported. Mount View schools were open for students Thursday, March 1.
