Update, 12:40 p.m.: Marlboro Mayor Jon Hornik said an active investigation is underway and the school is being swept by law enforcement. However, he said he doesn't believe the threat was a legitimate one and extra precaution is being taken in the wake of the explosions at the Boston Marathon yesterday.

A "suspicious note" has prompted the district to evacuate Marlboro Memorial Middle School shortly after 10 a.m. Tuesday, according to Sharon Witchel, a district administrator.

Two ambulances are at the Nolan Road school. The scene appears calm and organized as children are waiting on lines to be taken from the middle school by district school buses and transported to Marlboro Middle School. 

According to Witchel, the students are being bussed away in an abundance of caution and to allow the Marlboro Police Department to have easy access to the entire building while they investigate the incident.

She said she was unable to comment on the contents of the note, saying that it is part of an active investigation.

At this time, Witchel does not anticipate that the incident will impact dismissal time or the afternoon bus schedule. 

Once the scene has been cleared by police, students will be bussed back to the middle school, Witchel said. 

Nolan Road has been shut down by police.

A K-9 unit from the Monmouth County Sheriff's Office is also on the scene.
