SOMERS, N.Y. - Students at Somers Middle School can expect to see additional police officers on Monday after a threat was discovered in the boy's bathroom.

Schools Superintendent Dr. Raymond Blanch has been sending emails to parents throughout the weekend following the discovery of the threat on Friday.

District officials are calling the threat a "horrible adolescent prank" but are responding with additional police presence at Somers Middle School on Monday.

The main entrance of the middle school will be monitored by staff during arrival. The doors will not be opened until 7:20 a.m. and will be locked immediately after arrival of the last bus, Blanch said.

According to the district, at the end of the school day on Friday, students alerted staff to a statement written on the wall of the boy's bathroom that read: "I am going to shoot up the school" followed by a student's name.

On Sunday, Blanch said the student who's name appeared on the wall denied writing it and police believe the statement was written by a different student to get the student named in trouble.

"I want to commend our students who brought this information to the attention of the school administration," Blanch said. "It is very important that when any student see something they say something."

Blanch said Westchester Police interviewed students at home on Friday and Saturday but have been unable to determine who is responsible for the threat.

The investigation is ongoing.

"While this event appears to be a horrible adolescent prank, we will not take any situation lightly," Blanch said. "We are committed to ensuring the safety of our children."

Blanch encouraged parents to talk with their children about violence and to contact the school's counseling department for additional support if needed.
