The FBI is investigating after an electricity substation was set on fire and a power line was intentionally cut in Lonoke County.
The FBI is offering a reward of up to $25,000 for information about the incidents. Authorities say Entergy Arkansas reported a fire at its substation in Keo on Sept. 29.
The FBI says the blaze was intentionally set and someone scratched "YOU SHOULD HAVE EXPECTED U.S." into a metal control panel outside the substation.
On Sunday morning, First Electric Cooperative reported that two of its power poles were intentionally cut in Lonoke County.
The FBI and other authorities are investigating whether the two incidents are connected to an Aug. 21 incident in which a high-voltage transmission line was intentionally downed in Cabot.
