FBI investigates cryptic message, power grid attacks

The FBI is investigating after three power grid attacks occurred in Lonoke County in two months.
The first of the three happened in August, when a high-voltage transmission line in Cabot was intentionally brought down.
"Although no injuries resulted from this act, the placement of the line created a risk to the community," FBI spokesperson Kim Brunell explained.
Investigators have released a clue: a 250-foot cable recovered near the scene.
It's believed the cable, which has a diameter of one-half inch and an attached 15-inch eyebolt, could have been surplus, salvaged or stolen.
On September 29, a fire was intentionally started at Entergy Arkansas's Keo substation.
The message "YOU SHOULD HAVE EXPECTED U.S." was found on a metal control panel outside the station.
October 6, 10,000 First Electric Cooperative customers near Cabot were without power after lines on two poles were cut just before 7:30 a.m.
Investigators believe a tractor with an extendable arm and circular saw blade was stolen from a nearby property and used to cut the lines.
Investigators believe the suspect(s) have knowledge of electrical matters and the ability to operate a large tractor. There is also a $25,000 dollar reward for information leading to an arrest.
