A retired Delhi Police personnel's son was allegedly stabbed to death after an argument with some people on Tuesday afternoon in Uttar Pradesh's Greater Noida, police said.
The incident took place in the Dadri area and the victim has been identified as Sher Singh alias Sheru, whose father retired from the Delhi Police some years ago, they said.
"Sher Singh died in the attack and three suspects have been identified. Apparently, a fight had happened between him and the accused on Monday during which he had slapped one of the accused," Deputy Commissioner of Police, Greater Noida, Rajesh Kumar Singh said.
"Monday's argument had broken out due to a collision involving auto-rickshaws and it appears he was attacked because of that," Mr Singh said.
However, the police are probing other angles also and digging deeper to ascertain the exact cause behind the attack and efforts are underway to catch the culprits soon, the officer added.
An FIR has been lodged at Dadri police station in connection with the case, he said.
