Pooja had been married to Rahul Solanki (23) for one-and-a-half months when she discovered that her husband was having an affair with her sister Rinky (20), said a senior police officer.
When Pooja objected over the relationship, Rinky and Rahul allegedly hatched a plan to eliminate her so that they can get married, the officer said.
The duo yesterday strangulated Pooja with her dupatta at their home in Palam, he said.
She was rushed to a hospital in an unconscious state where she was declared brought dead.
Rinky and Rahul were today arrested after investigation and questioning of family members, the officer said.
