A Nepali national was shot dead in Sector 3 of outer Delhi’s Rohini sub-city, local police said on Monday.

The deceased was identified as 43-year-old Singh Bahadur.

The Nepali, who worked as security guard for a private enterprise, was on duty when the incident took place on Sunday night, a police officer told The Hindu.

“A case of murder has been registered and investigation has been taken up. Prima facie it seems to be a case of personal rivalry,” said Deputy Commissioner of Police (Outer) Vikramjit Singh.

The police are checking CCTV grabs from all premises near the crime spot. Several persons have been questioned in connection with the incident. However, the identity of the shooter is yet to be ascertained, said the officer.
