A Geraldton business owner who sexually harassed women across the country for almost 10 years using public payphones was found with more than 200 files of child exploitation material and bestiality, a court has heard. Christopher Andrew Anderson appeared via video link in Geraldton Magistrates Court on Monday, where he pleaded guilty to six remaining charges, including four counts of using a carriage service to menace, harass, or offend, one count of pursues another to intimidate and possess or copy an indecent or obscene article. The 58-year-old man previously pleaded guilty to 13 counts of the same carriage service offence, one count each of possessing child exploitation material, obstructing police officers and cultivating a prohibited drug, two counts of possessing a prohibited drug and three counts of obscene acts in public in July. The charges relate to alleged incidents which occurred as far back as 2013. Anderson was granted home detention bail but found himself back in custody after he was charged with using an optical surveillance device to record a private activity in August. Police opposed bail at the time, citing that a witness of the offence was currently residing in Anderson’s home detention house. Lawyer Julie Gray said they were still looking for an alternative bail address before making a new application. Police Prosecutor Paul Birkinshaw told the court a USB drive containing more than 200 files of child exploitation and bestiality material was found in Anderson’s possession on June 15 in West End. Anderson will reappear in Geraldton Magistrates Court on January 11 for a sentencing date to be set. A psychological report, pre-sentence report and psychiatric report will be prepared before sentencing. Speaking at the time of Anderson’s arrest in June, Geraldton police officer-in-charge Sen Sgt Chris Martin said Anderson had used Geraldton payphones to harass 15 women aged between 22 and 50 from across WA and Melbourne. The 58-year-old also performed sex acts in public while he made some of the calls. Upon a search of his home, police seized cannabis and child exploitation material. Sen Sgt Martin described the footage and photos as “some of the most explicit material you could find”.
