According to a statement by Wasim, a resident of Paharganj, his sister Rukhsar had called him on February 14 complaining that she was beaten by her husband Parvez, father-in-law Rahis and brothers-in-law Nadeem and Shoaib.
Wasim, along with his father and other relatives, approached a local to mediate and resolve the matter. Parvez, Rahis, Nadeem and Shoaib were also called there, police said.
Abdul Gaffar (50), Mohammad Sayid (42), Subhrati Khan (54), Amruddin (57), were injured in the attack. Sayid later succumbed to his injuries, the official said.
Yesterday, acting on a tip-off that the accused would reach Jahangirpuri Metro station, Rahis, Parvez and Rehan were arrested, DCP(north west) Milind Dumbere said.
During interrogation, the accused claimed that Wasim had picked up a knife and threatened them. Parvez allegedly snatched the knife and stabbed Wasim's relatives, he added.
