The woman, Sanjeeta Bara, who owns a placement agency, allegedly hired two rikshapullers and got her husband Manoj Bara (33) murdered on September 30 in Nihal Vihar, V Renganathan, Additional Commissioner of Police (West), said.
Sanjeeta was arrested yesterday while the hired killers, Sushil Bara and Bimal Kujur, were apprehended early today, the ACP said.
"Sanjeeta told us during questioning that she got her husband murdered. She said that her husband had illicit relations with many women and when she objected to such relationships, her husband used to beat her brutally. She had a fear of being murdered by her husband," Renganathan said.
She allegedly made a plan to murder Manoj before he murders her. She met Sushil and Kujur in a church at Punjabi Bagh and hatched the plan.
"She told them about the atrocities caused by her husband and fear of being killed. She asked them to murder Manoj and rescue her from his atrocities. The youths agreed and asked for Rs 1.5 lakhs which Sanjeeta agreed to pay after the murder of her husband," he said.
As per plan, Sanjeeta left Delhi for her in-laws' house in Jharkhand so that no one could suspect her. After reaching her village, she asked Sushil and Bimal to commit the murder, he said.
During investigations, Renganathan claimed, 27 suspects were interrogated.
