Her father described his daughter as simple and studious. He said she wanted to be a teacher and would spend her days tutoring children in their home in Delhi, before turning to her own studies.
The family said they had last spoken to Ms Brella by phone on 10 November.
She told them she had made dinner and was waiting for Mr Lamba to come home, her sister said.
Ms Dabas said her sister’s phone was off for the next two days and by 13 November they “thought something was wrong” and asked people they knew to file a complaint.
Northamptonshire Police said it was contacted on Wednesday regarding concerns for her welfare – and that led to the discovery of her body and the launch of a murder investigation.
Ms Dabas explained that her sister and Mr Lamba had entered into an arranged marriage, with a legal wedding held in August 2023. The couple then had their traditional Indian ceremony on 22 March of this year before they left for the UK around 30 April.
Mr Lamba was a student in London, she said, and her sister had been working in a warehouse.
Ms Dabas said her sister “didn’t live a very happy life in London”.
“She struggled a lot because of her husband,” she said.
