The Central Bureau of Investigation filed a charge sheet on Friday against all four accused in the alleged gang rape and murder case of a 19-year-old Dalit woman in Uttar Pradesh’s Hathras, officials said.

The top investigation agency invoked charges of gang rape and murder against accused Sandeep, Luvkush, Ravi and Ramu, their lawyer told reporters outside the local court in Hathras. The court has taken cognisance of the matter, he added.

The Dalit woman was allegedly raped by the four accused from an “upper caste” community in Hathras on September 14. She later died on September 29 while undergoing treatment at the Safdarjung Hospital in Delhi.

The matter came to national attention all the way more when the police handling the case cremated her body in the dead of the night near her home on September 30.

Her family alleged they were forced by the local police to hurriedly conduct her last rites. Local police officers, however, said the cremation was carried out :as per the wishes of the family”.

According to officials, the CBI looked into the role of the four accused men who are in judicial custody.

They were also put through different forensic tests at the Forensic Science Laboratory in Gandhinagar, they said.

The CBI investigators had also met doctors at the Jawaharlal Nehru Medical College and Hospital, where the victim was treated after the alleged gangrape on September 14, they said.

The Yogi Adityanath Government had faced a lot of flak for the case which was later transferred to the CBI.

The CBI had constituted a team to probe the incident and handed over the probe to its Ghaziabad unit.

The team has already recorded statements of family members of the victim.
