Extra security is on campus at Walter Panas High School in Cortlandt Manor following a reported threat by a student.
School officials said in a letter to parents that there were a number of rumors circulating regarding an incident at the school on Monday, March 18.
"This matter has been fully investigated and handled by the administration and the police and there is no existing threat to the school or community," school officials said in the letter. "As the public is aware, we cannot release the results of student investigations, however, we can emphasize once again these reported incidents were fully investigated by the school and by the police."
Westchester County Police said they became aware on Wednesday, March 20, that rumors were circulating on social media that there would be an incident at Walter Panas High School Thursday, March 21 and that students should stay home, said Kieran O'Leary, spokesman for the Westchester County Police.
The rumors stemmed from a previous dispute between two students, O'Leary said.
"Westchester County Police, including our School Resource Officer assigned to Panas, had investigated that original incident and also conducted additional investigation last night after the social media postings," he said. "It was determined that there is no credible threat to the school."
To alleviate any concerns that students or parents may have, additional county police officers are at Walter Panas today along with the SRO, O'Leary said.
The school said it is not releasing additional information because the concerns that continue to be raised "are simply not grounded in facts, and spreading false accusations, only makes matters worse"
They also said asked parents and students to trust that they have the matter in hand and that all safety precautions have been taken.
