UPDATE: Union-Endicott school officials have now notified parents that Endicott Police have tracked down the source of the social media threats and have determined them to be a prank.

ENDICOTT, NY – There’s a police presence at all Union Endicott School District buildings Thursday following a threat posted to social media Wednesday.

In a call to parents, Union Endicott Superintendent Nicole Wolfe said that a social media account had been hacked and 2 messages were posted Wednesday threatening violence during lunch Thursday at the high school.

As a result, the school is closing its campus at lunchtime and all high school students will stay in school.

Wolfe says there has been no information to corroborate the threats and that Endicott Police are investigating the situation.

Officers have been stationed at all Union Endicott schools as a precaution.
