A 40-year-old man has been arrested on accusations that he attached an improvised explosive device to a natural gas pipeline in eastern Oklahoma.

The FBI identified the suspect Friday as Daniel Wells Herriman of Konowa and said Herriman acknowledged making and placing the device Sunday on the pipeline and putting a timer on it set for 2 a.m. The device did not go off and there was no damage. FBI spokesman Clay Simmonds said the agency has no motive yet.

A federal complaint says the IED was discovered Wednesday on a pipeline at the Enerfin Resources substation. Company workers discovered the device. Herriman was arrested on charges of attempting to destroy property used in interstate or foreign commerce. Online court records did not indicate whether Herriman had an attorney.
