A UPS worker in California planned a mass shooting, police said Monday after finding 20,000 rounds of ammunition in his home. 

Thomas Andrews, 32, a Sunnyvale, Calif., resident, was arrested on charges of evading police, driving under the influence and several weapons violations, the Sunnyvale Police Department announced in a press release.

Police found multiple high-capacity magazines, five tactical-style rifles, one shotgun, three handguns, full body armor and tactical backpacks loaded with ammunition staged at his front door.

The police department was informed that Andrews allegedly sent threatening text messages to his employer at UPS. Authorities began investigating and learned he had four handguns and a rifle registered.

When officers encountered Andrews, the situation evolved into a vehicle pursuit until he was taken into custody.

“He alluded to a mass shooting in his text messages,” Sunnyvale police Capt. Dan Pistor told The Associated Press. “I definitely think we avoided a tragedy.”

A UPS spokesperson told The Hill in a statement that the company is "cooperating with law enforcement as they conduct their investigation."
