Council Rock High School South is closed today to students and staff as authorities sweep the school in relation to a threat that resulted in a student's arrest.

And earlier this week, a student was charged in a similar incident in Montgomery County.

At Council Rock, in Northampton Township, police took the student into custody yesterday, according to a school statement. The student's age and identity have not been released.

Authorities say the threat was specific to the school, which is located in the Holland section of Northampton Township, Bucks County.

As a precaution, police will perform a security sweep of the entire facility today.

No one will be allowed on the grounds until authorities give clearance.

School officials are asking students, parents and faculty to check the school's website (www.crsd.org) for updates.

And, on Wednesday, at Spring-Ford Senior High School, a student who was upset over a grade made several threatening statements.

He was charged with terroristic threats, harassment and disorderly conduct, said Limerick Police chief William Albany. The district has a zero tolerance policy. The district released a statement indicating disciplinary measures were also being taken.

Albany said while the student said he would "make last week look like nothing" referring to the Newtown shootings, police and school officials did not feel there was any imminent danger. The student did not have any weapons and there were none at home, he said.

"When criminal charges are filed, it gives the system a little more leverage," He said. The goal was to get the student help and the charges ensure the individual complies. The student is now in a treatment program, he said.

"I think this young man puts a lot of pressure on himself."

A similar incident happened a few weeks ago at the districts vocational education school and was handled the same way, Albany said.
