The CBI has taken over investigation into the alleged gangrape of a Dalit woman in Hathras, Uttar Pradesh on September 14, officials said.

The agency registered an FIR on Sunday morning under Indian Penal Code (IPC) sections related to gangrape and murder, they said.

The case was earlier registered at Chandpa Police Station, in Hathras district of Uttar Pradesh, on a complaint by the victim's brother.

"The complainant had alleged that on 14.09.2020, the accused tried to strangulate his sister in the millet field. The case has been registered by CBI on the request of Uttar Pradesh Government and further Notification from Government of India," CBI Spokesperson RK Gaur said.

The agency has constituted a team to probe the case, he said.

The 19-year-old woman died of severe assault injuries at Delhi's Safdarjung Hospital on September 29. She was allegedly gangraped on September 14 by four upper caste men.

Visit of fact-finding team of Left, LJD MPs to Hathras cancelled by UP police

The visit of a fact-finding team of Left and LJD MPs on Sunday to Hathras, following the alleged gang-rape and death of a Dalit woman, was cancelled after the Uttar Pradesh Police informed it that her family is being shifted to Lucknow for a court appearance, sources in the CPI(M) said.

The family members of the 19-year-old Dalit woman who died at a Delhi hospital after allegedly being raped by four men in Uttar Pradesh's Hathras district will appear before the Lucknow bench of the Allahabad High Court on Monday.

Barely half an hour before the team was to depart from New Delhi, the Uttar Pradesh Police informed that its visit had been cancelled as the woman's family is being shifted to Lucknow for a court appearance on Monday, the sources said.

The team, which comprises Elamaram Kareem and Bikash Ranjan Bhattacharya of the CPI(M), Binoy Vishwam of the CPI and M V Shreyams Kumar of the LJD, was to visit the Hathras rape victim's house and meet her family members, neighbours and others, they said.

The team of MPs also wanted to hold a meeting with the district magistrate and the district police chief to enquire about the safety of the woman's parents and relatives as there were incidents of "constant attacks" on the them, the sources said.

The fact-finding team had decided to submit its report to the president, the chief justice of India and the prime minister after the visit.

Shocked by the incident and her forcible cremation subsequently, the Lucknow bench of the Allahabad High Court on October 1 had summoned top government officials to court.

A division bench of Justice Rajan Roy and Justice Jaspreet Singh had ordered the Uttar Pradesh additional chief secretary, state police chief and an additional director general of police to appear before it on October 12 to explain the incident.

Taking suo motu cognisance of the case, which has triggered widespread outrage, the bench also ordered the Hathras district magistrate and superintendent of police to appear to apprise the court of various aspects of the case, including the ongoing probe into it.
