The suspect in the Ansonia High School threat that prompted school officials to issue a lock-in at all Ansonia schools on May 23 has plead not guilty to three charges on Friday.
Police arrested GianCarlos Diaz, 19, of Ansonia, and charged him with first-degree threatening, second-degree threatening and second-degree breach of peace. Police said he is a senior at the high school.
Diaz plead not guilty to all three charges.
Police said the threat was posted on the After School App and might have been directed at the Ansonia High School students.
In addition to the lock-in and a day of missed classes, police were stationed at all of the schools in Ansonia for the three days leading up to the Memorial Day Weekend.
Diaz will appear in court again on Aug. 5.
