Local law enforcement agencies have deployed more police at some schools as posts on social media and other locations have hinted at planned violence. 

The perceived threats coincide with the conversations about the end of the world Mayan Calendar and the one week anniversary of the mass murders at Sandy Hook Elementary School in Connecticut.

The Broome County Sheriff's office says any threats against a person, school district or public entity should be immediately reported. Officials say all incidents will be taken seriously.

The superintendent of the Owego Apalachin School District says a rumored threat Wednesday that had parents concerned is unsubstantiated. Still, Doctor Bill Russell said, while the rumor was determined to be false, law enforcement was requested to be at the high school for the day.
