A high school student in Maine accused of threatening a school shooting in posts on an online gaming site has been arrested.

Ellsworth schools Superintendent Daniel Higgins says the threat did not reference a specific school, but the website’s host provided the FBI with an IP address that led to an Ellsworth High School student.

Nineteen-year-old Michael Allen was arrested and charged with terrorizing.

Police Chief Glenn Moshier tells WCSH-TV the threat did not mention any specific time or date but was determined to be credible. He says the author of the messages estimated he could kill as many as 30 people and become “the most notorious person.”

Moshier says Allen was supposed to graduate from the school last year but has yet to meet a few non-academic requirements.
