Their 'foolproof' plan was busted when a police team which had stopped them for random checking spotted beard on a person draped in burqa.
"The Muradnagar police in neighbouring Ghaziabad detained three persons last night as they were transporting a body draped in a burqa to dispose it in Gang Nahar. The trio tried to misguide a police team that intercepted them but failed to do so," said Deputy Commissioner (East) Ajay Kumar.
The Muradnagar police later informed their counterparts at Jagatpuri police station who arrested Rabiya, Dilshad's wife who spilled the beans during investigation revealing that she suspected that her husband Dilshad was in an illicit relationship with a woman, police said.
"She shared her doubts with Habiba and her husband and they planned to hire the contract killer who was paid Rs 10,000 in advance for killing Dilshad.
"On the night of February 23, she gave milk laced with sleeping pills to her husband and called her three accomplices who then killed him by strangulation and took his body to Gang Nahar for disposal," he said.
