Shivani's complaint to the police names 12 members of Anshika's family and "60-70 unknown people".

A police official told the BBC that seven people, including Anshika's father and uncle and their sons, have since been arrested and remain in jail.

They say Anshika's father has lodged a counter-complaint accusing "Anshu, his parents and sisters" of harassing his daughter for dowry and murdering her.

Shivani denies the accusations against her family, although she admits that they had received gifts, including a car, from Anshika's family at the wedding. "They gave whatever they wanted to their daughter. We didn't ask for anything," she says.

Anshu has not returned home since the night his wife died. "He's in hiding because with most of Anshika's relatives out of jail, he fears for his life," she adds.

Dowries - both giving and accepting - have been illegal in India since 1961, but 90% of Indian marriages still involve them, according to a recent study .

Police receive thousands of complaints of harassment of wives every year and crime data shows 35,493 brides were killed in India between 2017 and 2022 for bringing in insufficient dowry.

But this kind of supposed gruesome revenge in a case of alleged dowry death is unheard of.

Shivani, who is now living with her uncle's family next door, takes us for a walk through what - until recently - used to be her home. The remnants of that night's tragedy are strewn about everywhere. The walls are blackened with soot and the floor is covered in thick ash, dotted with metal pots and pans and burnt out skeletal remains of furniture.

"I want justice. My life is ruined, my home and family are gone. I want a free and fair investigation and everyone who's found guilty must be punished," she says, adding, "Why did they burn the house down? How would we find any evidence now?"
