Police arrested an 18-year-old Westwood Jr./Sr. High School student who allegedly made threats against another student Wednesday.
Westwood and Washington Township Police conducted a joint investigation. A borough home was searched and some evidence was collected before the arrest was made, according to a press release from Westwood Police Chief Frank Regino.
Regino said he could not specify what was taken from the home due to an ongoing investigation, but said that the man had been charged with possession of an imitation weapon.
"At this time we do not believe that there exists any threat that could be carried out against the schools in the district," Regino said in the release.
As of Friday, the student's identity was still being withheld because he was undergoing an evaluation at an area hospital, Regino said.
Washington Township Police Chief Randy Ciocco said two students would not be allowed back to the school until "evaluations are performed."
School administrators were alerted to the threat shortly after school Wednesday, according to a school messenger phone call to parents from Acting Superintendent Rory McCourt.
"The nature of the threat did not indicate an immediate threat to the school," McCourt said in the message.
McCourt wrote in a letter to parents that all schools in the district had reviewed "protocols for supporting students" and that district staff had been "vigilant about maintaining a single point of entry" to Westwood Regional schools since the shootings at an elementary school in Connecticut last week..
In a previous letter, McCourt also wrote that the district was working with local police to increase security.
McCourt thanked Westwood and Washington Township Police in his letter and reaffirmed that the district was working with them to improve security.
"Considering the anxiety that I’m sure we are all feeling as parents, I wanted to reassure you that your children had a positive experience today at school," McCourt wrote.
