Mushtaq Ahmad Dar and his two sisters -- Nasreen and Misra -- were arrested after the trio admitted to strangulating their 20-year-old sister Zubaida to death in the fields at
Shoolipora in Budgam district on August 24, a police spokesman said.
"During investigations, Dar, the brother of the deceased, disclosed that he and his two sisters were not satisfied with the behaviour of Zubaida and were facing a lot of humiliation in society by her deeds," the spokesman said.
Dar and his sisters hatched a conspiracy to kill her and took Zubaida to the fields, and later strangulated her to death with her scarf, he said.
The spokesman said the police was also probing other aspects including grabbing of money belonging to the deceased.
