(WPXI) – A North Dakota man has been indicted by a grand jury on child pornography and sex exploitation of a Peters Township girl. 27-year-old Nicholas Nesdahl, a diesel mechanic, pretended to be a 15-year-old boy on the app Omegle – an app that boasts about connecting strangers. Police say Nesdahl asked a 13-year-old girl to sexually assault a six-year-old child and send him those videos. Authorities say the case began in October when police in Peters Township got a complaint from the mother of the 13-year-old, who discovered the videos on her daughter’s phone. Nesdahl is facing six counts of production and receipt of child porn and is being held in North Dakota, pending extradition to Pittsburgh. Police say the 13-year-old has also been arrested. The six-year-old is not facing any charges.
