A florist was shot dead after a quarrel broke out between him and the accused in northeast Delhi's Welcome area, police said on Monday. The incident took place on Sunday night.
At the Guru Teg Bahadur Hospital, Mehtab (40) was declared "brought dead" by doctors.
Earlier in the day, Mehtab had a quarrel with one Nawazish, Deputy Commissioner of Police (northeast) Atul Kumar Thakur said. In the night, Nawazish and some of his associates came and fired upon the victim, the cop added.
A murder case was registered in connection with the incident and two of the accused -- Nawazish and Salman -- were apprehended, the DCP said. A weapon was also seized from their possession.
The accused told the police that they killed Mehtab to take revenge as he had picked up a quarrel with their father, Thakur said.
The exact cause of the quarrel that had triggered the incident was being ascertained, the top cop said.
