Paramvir Singh, son of the deceased, said a roll number was also written on a piece of paper. "We have checked and found that the questions that were written on the piece of paper appeared in the question paper," said Paramvir.
"It is possible that my father caught Parminder Kaur helping students and was about to take action against her, so she, along with her accomplices, harassed his father so much that he committed suicide by jumping into the canal," he added.
The family has handed over the piece of paper to the Malaud police. The family suspect the accused could harm them. The family has also filed another complaint with the police about their safety.
Manjit Kaur, wife of the deceased, said that as the accused were influential, they could harm the family. She has demanded security for the family.
Malaud SHO Harjinder Singh said the police had already arrested accused Happy Sattu and launched a manhunt for others. He said Parminder Kaur had applied for bail in the local court, but her plea was dismissed. Paramvir also alleged police inaction.
