Man charged with sexually assaulting a 10-year-old girl at her home in France has been identified as the father of a two-year old girl, a court heard.
The alleged victim told police she was abused at a home in the Paris suburb of Alsace-Moselle last September, when her father, who is an Austrian, was visiting.
Police said the boy, who was not identified, is being held in custody on suspicion of raping the girl.
He is due to appear in court on Monday, while the girl will be interviewed.
Her father, identified as Andreas, has previously denied the allegations.
He was charged with raping the child at his home on September 30.
He has been charged with rape and sexual assault, which carries a maximum sentence of five years in prison, and is expected to appear before a court on the same day.
The girl’s mother, who has asked to remain anonymous, said she had been sleeping in her apartment when her daughter went to wake her.
The court was told she saw the boy standing over the child, who appeared “unwilling” to give him permission to enter.
Police also found a knife in the house, which was also believed to be used to sexually assault the girl, who suffers from cerebral palsy.
The accused, who also faces a child protection charge, is expected face charges of aggravated assault.
