YORK COUNTY, Pa. (WHTM)– There will be an increase in law enforcement presence out of caution after the Spring Grove Area School District received a false threat, according to police.

Northern York County Regional Police said that there was no evidence to back up a “vague” threat that was made against the school district, according to a Facebook post.

“The District and NYCRPD School Resource Officers have fully investigated the threats and have found them to be unsubstantiated,” the police department wrote in a statement.

Officials were made aware of a note within the district that involved a threat against the schools.

Extra police officers and patrols will be present in the district on Thursday out of an abundance of caution, police wrote.
