There will be an increased law enforcement presence Friday at Steele Canyon High School in Spring Valley as a precaution in response to a shooting threat authorities said they believe is not credible.
The school resource deputy assigned to the school received information around 8 p.m. Thursday about an image being circulated on social media by students, said sheriff's Lt. Tom Seiver.

The image was a picture of a threatening message written on an unknown surface, at an unknown location, and was taken on an unknown date, Seiver said. The message threatened a school shooting but did not reference a specific school, according to Seiver.
The school was searched in an attempt to locate the original message but the message was not found, Seiver said.

"At this time, there's no credible threat to the Steele Canyon High School," Seiver said. "As a precaution, deputies will have an increased presence at the school on Friday. The Rancho San Diego Station is working closely with school administration to investigate the source of the message."
