Rapid City authorities arrested 26-year-old Andrew Hiipakka Tuesday afternoon on eight counts of possession of child pornography.
A tip last week led to a search warrant at his home. That's when detectives with the Internet Crimes Against Children Task Force found numerous images of child pornography on Hiipakka's personal computer.
Detectives also say Hiipakka was employed as a teacher at St. Thomas More Middle School. Hiipakka was immediately terminated from his job by the Rapid City Catholic School System.
Anyone with information related to this investigation is urged to contact the RCPD Criminal Investigations Division at 394-4134.
