The Goa Children's Court has acquitted Rohit, son of state Education Minister Atanasio Monserratte, on the charge of raping a German minor girl.
Rohit was arrested in November 2008 for allegedly raping a 14-year-old German girl and sending her lewd messages.
The court acquitted Rohit on Wednesday as the mother of the victim and the girl refused to cooperate with the prosecution.
Both have returned to Germany and were not available to testify before the court.
The victim's mother even refused to make available the birth certificate of the girl, which would have worked as a proof of her age.
Rohit was accused of raping the victim in his car at Bambolim, a town near Panaji, and then sending her lewd messages.
The victim's mother lodged a complaint with Calangute police on October 2, 2008, but Rohit remained absconding till he surrendered on November 4, 2008.
The court had given time for the prosecution to seek help of the German consulate for recording the statement of the victim and her mother. But neither of them cooperated with the authorities.
