ROSEVILLE, CA - A bomb threat made at Roseville High School on Sunday turned out to be a long-distance April Fools Day joke, according to Roseville police.

A police perimeter was set up at the school around noon after an individual called police at least twice from a cell phone.

"He said he there was a pipe bomb in the cafeteria, injured students, and that he had shot a couple of kids--just random crazy stuff," said Sgt. Darin Defreece of Roseville Police Dept.

Defreece said initiallya dispatcherreceived a call of a juvenile with an assault rifle on campus and gunfire cold be heard in the background.

Units from the Roseville, Rocklin, and Citrus Heights Police Departments all responded to the school, along with officers from the California Highway Patrol. A helicopter, several paramedics, and firefighters also responded. Roseville police officers on scene said an Active Shooter Team was also deployed to the school in response to the threat.

Arriving personnel cleared the entire campus on arrival and searched for any signs of an explosive device, but found nothing.

"It's a waste of taxpayers' money. It's horrible. It's stupid someone did that," said resident Tamara Rushton.

It was later determined that the calls had been made by a 30-year-old autistic man in Virginia as an April Fools Day prank, said Sgt. Cal Walstad of Roseville Police Dept.

The man had made similar pranks previously with other law enforcement agencies, Walstad said.

According to Walstad, authorities in Virginia were dispatched to the man's home.

Roseville police clarified that the prankster will be paying for the cost of response, and not local taxpayers. The suspect will face civil and felony criminal charges according to Defreece.

"It's never a good idea to prank call a police department," said Defreece. "We will find you."
