Prime Minister Narendra Modi on Sunday said atrocities against women are an unpardonable sin and those involved in the crime should not be spared.

Addressing Lakhpati Didi Sammelan event in Maharashtra, Modi said the safety of the women is a top priority of the nation along with their empowerment.

Modi said, “I understand the pain and anger of my sisters and daughters, irrespective of the states.”

Taking a tough stand, the Prime Minister reminded all the state governments and the political parties of the country that atrocities against women are an unpardonable sin and the guilty and his accomplice must not be spared.

Modi made the remark amid the ongoing protests across the nation over the rape and murder of a PG trainee doctor in Kolkata's RG Kar Medical College and Hospital.

The Prime Minister remarked that public institutions, be it a hospital or a school or an office or the police system, should be made accountable and any sort of negligence on their part was unacceptable.

Modi said, “Governments may change, but our biggest responsibility as a society and as a government should be to protect the life and dignity of women.”

The Central Bureau of Investigation (CBI) conducted searches at 15 locations across Kolkata on Sunday morning in connection with allegations of financial irregularities against RG Kar Medical College's ex-principal Sandeep Ghosh, following the brutal rape and murder of a junior doctor at the hospital premises.

According to reports, a CBI team reached Ghosh's house at 6.45 am, but he opened the doors to them only at 8 am.
