Out of the two absconding contract killers, Raja, surrendered before the police today.
The gory incident had come to light when the body of 45-year-old Munawwar Hassan with gunshot injuries was found at his residence in Burari on May 20 after his friend Sahib Khan alias Bunty informed the police about his death.
Hassan had been lodged in Tihar jail for a rape case since January 19 and was released on interim bail on May 17 as his wife Sonia and four children, Aqib, Shaqib, Arzoo and Arshi, had been "missing" since April 18.
He was known to Hassan and his family for the last several years. He was the deceased's confidant and business partner.

More than a month after they went missing, police had recovered the highly decomposed bodies of Hassan's wife and two daughters from Daurala village in Meerut a few days back.
Bunty had got Hassan, his wife and four children killed in order to take over the latter's property worth over Rs two crores. Bunty was arrested along with three men who had carried out the killings.
Bunty told police that on April 20, he took Hassan's wife and daughters to their relative's house in Saharanpur. While returning to Delhi, he killed them with the help of a contract killer.
On April 22, when Hassan's sons reached Bunty's office in Burari to inquire about their mother and sisters, they were also killed and their bodies were buried there.
