The teen, who according to reports is mentally-unstable, appeared before a magistrate and was remanded at the Bordelais Correctional Facility.
It is alleged that on May 22, the young man violated the child at a laundry in Micoud sometime after she went there to bathe, in order to get ready for school.
Reports are that the child was approached by the 18-year-old and told to give him a hug as it was his birthday.
The child refused and attempted to run out of the bathroom but the young man grabbed her and had anal sex with her.
That incident has left the entire community in shock. The alleged perpatrator was reportedly beaten before being given up to police. He was charged with unlawful sexual connection.
