According to police, the incident took place last night when the victim, Vikas Solanki, entered into a heated argument with his younger brother, Pawan, 20, who was later joined by their cousins Rahul, 22, and Ekraaj, 28.
The argument turned into a violent scuffle and Vikas was stabbed multiple times by the trio. Vikas's wife, Poonam, who was carrying their two-day-old daughter in her arms, was a witness to the incident. But before she could raise an alarm, the trio fled the scene, police said.
Vikas, who owned an internet cafe at Aman Vihar, used to ill-treat his father because of a dispute over a 100-odd square-yard plot, which the family inherited, the DCP said.
During interrogation, Pawan told police about the family dispute and how he was infuriated by Vikas's aggressive attitude towards him and their father. After the fight broke out last night, he called up his cousins, who stay at Aman Vihar, and the trio stabbed Vikas with a knife in a fit of rage, he said.
The body was handed over to his family after post-mortem, the official added.
