Ratan Lal, aka Ratan Singh, of Palwal, had been sentenced to death by a Faridabad court in 2004 for sexually assaulting and murdering the six-year-old son of Yadaram, whose brother Hari Singh, also of the same region, had filed the complaint against Ratan in 2002, a police officer said.
In 2006, Ratan's father Ranga Lal filed an appeal in Chandigarh High Court and got the sentence commuted to life term, the officer said.
Based on preliminary investigations, it was found that Ratan's birthday was January 8, 1983 according to his school certificate, while the birth certificate produced in court showed it as August 26, 1986.
A case has been registered against the accused and further investigations are on, the officer said.
