In her suicide note, the girl mentioned harassment by police and the fact that she was being pressurised allegedly by them to compromise with the rapists.
She alleged that she was also being threatened by rapists, who were roaming freely. The accused have been arrested.
Punjab Chief Minister Parkash Singh Badal on Friday constituted a high-level team headed by Additional Director General of Police (crime) Jaswinder Singh to visit the village to probe the matter.
