A report in the Daily NonPareil says a Pottawattamie County man was arrested Thursday in Nebraska, for allegedly making terroristic threats against several agencies. Pott. County Sheriff Jeff Danker told the paper 56-year old Paul Grindstaff, of Crescent, was arrested in Omaha after allegedly sending threatening emails Wednesday. Danker said he believed the emails were a response to a custody dispute Grindstaff was involved in concerning his granddaughter.

The emails were not targeted against anyone specifically, but they allegedly contained statements that alluded to the Sandy Hook school shooting and the shooting rampage of ex-Los Angeles Police Department Officer Christopher Dorner. Danker said the mention of those two events certainly caught law enforcement’s attention.

Pottawattamie County Attorney Matt Wilber said he could not comment on the specifics of the investigation, but he confirmed Grindstaff was apprehended by the Metro Area Task Force Thursday morning and arrested on warrants for suspicion of terroristic threats and first-degree harassment. Wilber told the paper that because Grindstaff was arrested in Omaha, the arrest affidavit will not be released publicly until Grindstaff is returned to Pottawattamie County.
