Eleven active shooter hoax calls were made to school districts throughout Maine, officials confirmed during a press conference outside Sanford High School.

Sanford communications coordinator Jordan Wilson says a call came into the Regional Communications Center around 8:20 a.m. Tuesday. The call came from an untraceable number, reporting there was an active shooter dressed in a black coat and black pants with a gun on the first floor of the high school. The caller told authorities they were locked in a staff room.

"Those initial complaints were detailed in nature, and they highlighted supposed active shooter scenarios in our schools, right here in the state of Maine," Maine Department of Public Safety Commissioner Michael Sauschuck said.

WMTW has confirmed threats were made at the following school districts: Fort Fairfield, Rockland, Portland, Gardiner, Wiscasset, Ellsworth, Sanford, Brunswick, Winslow and Houlton.

As an investigation into the hoaxes throughout the state continues, Sauschuck said he is proud of the first responders in the state: "Officers will respond. They will go through the door. They will protect the residents of Maine."
