Two men were killed and another sustained injuries after two unidentified people opened fire on them in west Delhi's Mundka area, police said on Tuesday.
The incident took place on Monday, they said.
All three were residents of JJ Colony, Bakkarwala, and were taken to hospitals where doctors declared Mangal (60) and Joginder (42) brought dead while Mohan Lal (62) is undergoing treatment, police said.
Teams from the crime and forensic science laboratory have inspected the spot of the incident and found six empty cartridges and three live cartridges. A helmet belonging to one of the assailants was also found on a slab at the entry point of the street, Deputy Commissioner of Police (outer) Sameer Sharma said.
The CCTV footage was analysed and two men in the age group of 25 to 28 years were seen coming from Bakkarwala village at 9.05 pm and after a few minutes, were seen running back, the officer said.
One of them was wearing a black cap and another had tied a muffler on his head, the DCP said.
According to Lal, he along with Mangal had gone to Joginder's house where one more person was also present, police said.
Around 9 pm, two men came there and asked about the residence of Satish -- Joginder's deceased father.
As Joginder pointed towards the photo of his father, the assailants opened fire. Joginder and Mangal fell down while Lal ran inside the house, they said.
A case under sections 302 (murder), 307 (attempt to murder) and 34 (common intention) and Arms Act has been registered at Mundka police station. Section 120B (punishment of criminal conspiracy) was also added in the case, police said.
Joginder was from the Sansi community and involved in three cases of the Excise Act, while his wife was involved in two cases of the Excise Act, police said.
Mangal had a tent business and Lal is an e-rickshaw driver.
During investigation, one person was interrogated near the spot who said he was receiving extortion calls for the last one month from a man. Therefore, section 120-B IPC has been added in this case, police said.
Without revealing his identity, the police said this person who was interrogated by them was likely the target of the assailants who may have killed the wrong persons.
However, the truth will only come out once the accused is arrested, they said. "The investigation is underway. We have some leads and are working on it. When the accused will be arrested, it will be more clear whether the deceased were the target or not and its reason," they said.
Mangal's son Sonu Singh said, "I work as a loader in a factory in Mundka. I was at the factory when I received a call that my father had a fight with someone. Later, a person in the area informed me that the matter was serious and when I reached the hospital, I got to know that he has died. He had no enmity with anyone."
