Tensions were running high Thursday morning at Northern Lehigh High School in Slatington as police investigated escalating conflicts among students.
Officials said it started when two groups got into a fight off campus Tuesday, and the clash continued with threats through social media.
Superintendent Mike Michaels told 69News that there was no fight or threats made in or on school property.
He said Slatington Police were called to the high school to address student concerns over threats made via social media after a fight in Walnutport.
Slatington Police Chief Dave Rachman said two suspects are being questioned--one is a student and one is in an alternative school in the district. Both are juveniles.
Rachman said officers were stationed in and around the school building and grounds.
Police presence is scheduled for the remainder of the school day Thursday and Friday as a precaution.
According to school officials, students were kept in first period for extra time Thursday morning, but as of 11:20 a.m., school was operating normally.
Students who didn't feel safe were allowed to go home Thursday after contacting their parents.
