The FBI is investigating at least five attacks on electricity substations in the Pacific northwest similar to one that caused widespread power outages in North Carolina.

Representatives from Puget Sound Energy, the Cowlitz County Public Utility District and Bonneville Power Administration confirmed the attacks took place in November, although the FBI declined to confirm the investigations and it's not clear whether any of the damage resulted in service disruptions, reported the Seattle Times.

“BPA is actively cooperating with the FBI on this incident and has encouraged other utilities throughout the region to increase their vigilance and report any suspicious or similar activity to law enforcement,” said Douglas Johnson, a spokesman for BPA.

Johnson declined to give details about the equipment that was damaged, but he said a “deliberate physical attack” at a Clackamas, Oregon, substation damaged a fence and equipment over the Thanksgiving holiday.

A spokesman said two Puget Sound Energy substations were damaged last month but declined to provide details, and a spokeswoman said two Cowlitz County Public Utility District substations in Woodland, Washington, were damaged by vandals in mid-November but have since been repaired.
