WILLIAMS, Ariz. -- Three people were arrested Wednesday after allegedly harassing a Coconino County resident by setting off explosive devices.
Coconino County sheriff's deputies arrested Phoenix resident Victoria Mast, 18, and northern Arizona residents Jose Hernandez, 20, and Christian Campos, 18, on weapons misconduct and harassment charges.
A man living in an unincorporated area of Coconino County, near the town of Williams, reported hearing explosions outside his home on four different occasions in January.
Investigators responded and each time found plastic bottles, which had apparently melted from chemical reactions and subsequent explosions. The sheriff's office said the explosives were created with some type of volatile chemical compound and sealed with aluminum foil.
Investigators have not said why the man might have been targeted.
While investigating the second incident on Jan. 22, deputies contacted federal agents with the Bureau of Alcohol, Tobacco and Firearms.
An officer with the Williams Police Department told deputies he had observed the three suspects in the area of the neighborhood where the explosives were set off.
The sheriff's office said the three suspects made a statement during interviews with deputies implicating themselves in the crimes.
