The then eight-year-old identified as Dilison Steve says in the complaint that he and his father had been travelling in a vehicle at the time of the abduction.
The now 17-year-old says his father was a human rights activist.
The UNHRC has not inquired from him as to why he had waited 10 years to lodge a complaint.
He had been taken to the UNHRC session by the Eelam organization in France.
At the session in March this year, the UNHRC received another complaint, by a girl identified as Jeyani Thiagaraja that her brother had been abducted.
