A 15-year-old boy was arrested Sunday for allegedly posting death threats on social media aimed at students at schools in the Santa Clarita Valley, authorities said.

Los Angeles County sheriff’s deputies began investigating the threats late Saturday after receiving phone calls about posts on Instagram from someone threatening to shoot high school students on an unspecified date, authorities said.

Deputies arrested the boy after serving a search warrant at his home Sunday morning, said Lt. Tom Bryski. The boy's name has not been released.

The posts, which have since been deleted, included threats against women and minorities, authorities said.

“We are aiming our guns mostly at high school students … blood will be shed and families will suffer,” one post said, according to KTLA.

The posts also included photos of guns, dead bodies and a school marquee for a “Valencia High School,” all later found to be stock images found on the Internet.

“Valencia High School has been nominated to be shot up first,” said another post.

The photo depicting Valencia High School was not of the school in Valencia, but an out-of-state school with the same name, authorities said.
