As California drought conditions worsen, water thieves are on the rise. One drove off with a 500-gallon water tanker in the Oakland Hills in March. The Marina Landscape tanker was resting on a trailer parked in front of a job site near the Caldecott Tunnel and police believe a thief hooked it up to a truck and drove off. The tanker is worth $4,500 to $5,000 and authorities suspect the thieves will use it to steal more water.

Last month, Sacramento police caught two men who illegally tapped into a city fire hydrant to fill a 2,000- to 4,000-gallon water truck they’d rented, the Sacramento Bee reports. Officials are determining whether the men had simply forgotten to obtain a permit or were intentionally stealing water.

This month the owners of a nudist resort in the Santa Cruz Mountains were charged with theft after piping water from a nearby creek despite many warnings from Midpeninsula Regional Open Space District to stop, the San Jose Mercury News reports.

Also this month, water bandits pried open locks on water spigots at a shopping center in Milpitas, CBS reports. Witnesses noticed three to four people filling containers in the middle of the night and the property owner confirmed the incident by looking at his water bill and noticing a significant jump in water use.
