On Monday, Uttar Pradesh Police arrested a 20-year-old woman named Anjali for killing her two minor sisters after they found her getting intimate with her partner in the Balrai area of the Etawah district.

The accused also tried to destroy the evidence of the murder, police said on Monday.

The minor girls found Anjali getting intimate with her partner in the absence of their parents, following which she killed them, they added.

The bodies of seven-year-old Surbhi and her four-year-old sister Roshni were found in separate rooms of their home on Sunday.

Anjali used a spade to kill her sisters. She washed the spade and cleaned her clothes after the murders, Additional Superintendent of Police (Rural) Satyapal Singh said. However, forensic examinations revealed blood traces on the spade and the accused’s clothes, he added.

Anjali has confessed to her crime during questioning, the officer said.

The girls’ parents were not at home at the time of the murders.
