The man from Enga was committed by the Waigani District Court for trial this week after enough evidence was found in court against him.
He is expected to appear at the Waigani National Court on Nov 8 for listing where a date will be set for his trial once the appropriate court documents are fixed.
The alleged incident took place on May 9 this year at the barracks where the man worked as a cook in its mess and the boy lives with his parents.
It is alleged he invited the boy who was hungry at the time into the mess saying he will be given food and money but sexually assaulted the boy instead. He gave the boy his mobile phone and threatened him not to tell his family.
The next day he went to the boy’s family home and asked for his phone in return which was where the boy revealed what allegedly took place the previous day.
He was later arrested by police regarding the incident.
