"Director General of Police has announced a reward of Rs 50,000 for a person who will provide information about the accused involved in the Vasco rape case," Goa police spokesman John Aguiyar told PTI.
State police have already formed a 15-member special investigation team (SIT) to track the accused, who has been at large after committing the sexual assault.
The girl was allegedly raped in the school toilet on Monday in Vasco, following which massive protests were witnessed in the port town.

Police had prepared a sketch of the accused yesterday but a fresh graphic was released today by them after questioning various eye witnesses.
The statement of the victim was also recorded by police.
