(Sacramento, CA) — Flights at the Sacramento International Airport were delayed for hours Thursday due to an intentional internet outage caused by someone cutting AT&T wires. The wires were deliberately cut nearby, affecting flights from Southwest and Delta Airlines.

The sheriff’s office is investigating. Crime scene investigators were seen photographing the area and dusting for prints.

Charges could range from felony vandalism to more severe charges depending on the motive behind the act. In a statement, AT&T says it has restored internet and wireless service to the Sacramento International Airport area following a fiber cut which they say appears to be an act of vandalism or attempted theft.

Sac International advises travelers to contact their airlines for more information on their flight or any continued delays.
