A Douglas County corrections sergeant was jailed Thursday in Iowa as part of an investigation involving federal authorities.

Investigators arrested Shawn Beu, 36, of Council Bluffs on suspicion of sexual exploitation of a minor, which is a felony, and possessing sexually explicit material regarding a minor, which is a misdemeanor, police said.

Beu was booked Thursday morning at the Pottawattamie County Jail, according to the jail’s website. His bail is $10,000.

According to a police press release, the investigation began after the National Center for Missing & Exploited Children passed a tip to the U.S. Department of Homeland Security, and that tip was investigated by the federal department and by Council Bluffs police.

Evidence obtained during the investigation was used to apply for an arrest warrant for Beu and a search warrant for his home.

On Thursday, both agencies executed the search warrant on his home and arrested Beu.

Bluffs police would not elaborate, citing the ongoing nature of the investigation.
