The teen was arrested Monday night and charged with creating a false public alarm. The alleged incident happened Friday at West Morris Mendham High School.

The Daily Record reports a judge ruled Tuesday that the teen will remain at the county's juvenile detention center until a December 16 hearing.

At Tuesday's proceeding, the teen's defense lawyer told the judge no evidence has been produced to show the teen has access to any weapons.

On Sunday, the Morris County prosecutor's office said enhanced security measures would be in effect for the start of the school day Monday, but didn't give details.
