Ansonia police have arrested a suspect in the Ansonia High School threat that prompted school officials to issue a lock-in at all Ansonia schools on May 23 and cancel classes on May 24.
Police have 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.
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.
On Friday, police obtained an arrest warrant and took Diaz into custody.
He was processed and released on a $5,000 non-surety bond and he is due in court on June 17.
