Washington State authorities said that several electrical power stations were victims of a  “coordinated attack” on Christmas. 

In a news release, the Pierce County Sheriff’s Department (PCSD) said its deputies were notified in the early morning of three reported robberies on Sunday at two Tacoma Public Utilities (TPU) substations and at a Puget Sound Energy (PSE) substation. 

Authorities added that all energy substations were broken into and some of the substations’ equipment was either vandalized or damaged during the incident. 

PCSD said that at least 14,000 customers saw their power cut off due to the coordinated attack. 

“At this time deputies are conducting the initial investigation. We do not have any suspects in custody,” PCSD said in its news release. “It is unknown if there are any motives or if this was a coordinated attack on the power systems.”

The sheriff’s department also said that its deputies received a call about a fire happening at another PSE substation. The fire erupted after suspects gained access through the fenced area and vandalized the station’s equipment.
