A threat made on social media Wednesday concerning Apollo High School has been investigated and an arrest was made out of state. In a notice sent to parents, it was revealed that law enforcement agencies have determined that the threat was not credible and there was not a legitimate threat to DCPS schools. The messages originated from Arizona. A subject has been arrested in Arizona as a result of a similar threat made to Mt. Vernon High School in Mt. Vernon, Indiana. Officials said they don’t have a clear picture as to why a DCPS student was chosen by the Arizona suspect. They went on to say that few details can be released regarding the juvenile suspect.
