SALINA, Kan. -

Information that alleged a general threat was found at Central High School according to officials with Salina Public Schools.

In a press release, Bill Hall, the school superintendent says a note was found Tuesday, April 15, by a staff member giving a vague description of a violent act that will be committed in the school.

The following day, a cell phone was found in one of the school offices that appeared to have been shot with a firearm. Police say they aren't certain the two events are connected.

They said the school along with Salina police department are taking extra precautions to ensure the safety of students and faculty. Those precautions include increased police presence, school walk-throughs, and monitoring access to the building. The release didn't say how long the added security measures will be in place.

The incident is still being investigated. Central High School is open and will remain open because of the extra precautions that are in place.

On Thursday, there were about 150 students not in attendance, but it is uncertain how many of them are gone because of the threat.  Jennifer Jimenez decided to keep her freshman from going to be school just to be safe.

"I didn't want to send him to school, I was too scared," Jimenez said. "To me, it's better to be safe than sorry."

Anyone with information is asked to contact the Salina Police Department, Salina school officials or Crimestoppers at (785) 825-8477.
