SAN DIEGO (KGTV) - Security was increased Thursday morning at three San Diego County schools after each campus received threats the day before.
While authorities and school officials considered the supposed threats on social media unsubstantiated or not credible, extra law enforcement officers were present at the three schools as a precaution.
The three schools that received threats were Vista High School, Madison High School and Innovation Middle School.
In a voice message sent to parents Wednesday night, Vista High School Principal Anthony Barela addressed a threat made against his school on social media. The message, titled "Urgent Message - School Safety," reads:
"I am calling to let you know that earlier today we were informed of a social media post and speculation of a possible school shooting tomorrow.
While there is no credibility to this threat and nothing to substantiate a threat to Vista High School - as a precaution there will be extra law enforcement on site tomorrow. Law enforcement is actively investigating this threat.
All of these rumors are unsubstantiated. We are taking them very seriously with extra security on campus and a focus on safety for each and every one of our students."
The parent of a student in the San Diego Unified School District saw 10News' Facebook post about Vista High and sent the following message from the principal of Madison High School:
Dear Madison Families:
In light of the events at Marjory Stoneman Douglas High School last week, I want to communicate that we are actively investigating a potential threat to our campus that was posted on social media.
San Diego Unified School Police has been investigating this matter and does not feel there is a credible threat to our school.
However in an abundance of caution, School Police will have additional officers at the school first thing in the morning. I want to assure you that we take the safety of everyone on our campus seriously.
If you have any concerns, please contact me at 858-496-8410.
Respectfully,
Principal Nash
The same parent notified 10News that parents at Innovation Middle School also received a message about increased security. The message reads:
Dear Innovation Middle Families:

San Diego Unified School Police has been investigating this matter and does not feel there is a credible threat to our school.

The unsubstantiated threats come one week after a gunman carried out a shooting at Marjory Stoneman Douglas High School in Parkland, Florida, that left 17 people dead.
Earlier this week, security was heightened at San Marcos High School after a threat was made on social media. However, the post did not appear to specifically target the North County school.
Police also responded to a threatening message written in a restroom at High Tech High Media Arts in Point Loma, but the message did not appear to be credible.
