BURLINGTON, Kan. (AP/Salina Post) — Authorities have arrested an eastern Kansas sheriff’s deputy after an investigation into child sex crimes.

An investigation by agents from the Kansas Bureau of Investigation (KBI) has led to the arrest of 28-year-old Matthew G. Vander Linden, a deputy of the Coffey County Sheriff’s Office, according to a media release.

Vander Linden was arrested Tuesday afternoon for two counts of unlawful voluntary sexual relations, one count of electronic solicitation, and one count of sexual exploitation of a child. The arrest took place without incident at the Coffey County Sheriff’s Office.

The KBI said in a news release that its agents began to investigate last week at the request of the sheriff’s office. The release says the deputy has been terminated. He had worked for the sheriff’s office since March 2014.

The KBI says its investigation is ongoing.
