Rocky had acquired the licence from Delhi Police on June 12, 2013. As his address proof, he submitted the documents of a rented house in south Delhi's Vasant Kunj area, a senior police official said.
Earlier on Friday, in a counter-attack on the Centre, Bihar Deputy Chief Minister Tejaswi Yadav demanded to know how Rocky got the licence for his pistol without proper verification in Delhi, and called for a thorough probe into the matter.
Delhi Police is under the Centre, hence, they need to explain about the issuance of license in violation of rules, the RJD leader said.
The developments compelled the licensing unit of Delhi Police to dig out records, following which it emerged that while applying for license, Rocky had submitted a written statement claiming to be the executive director of a private construction company.
"Rocky also claimed that the company took up several government contracts for construction of roads and other facilities in left-wing extremism-affected areas for which he faced threat to life," the senior official said.
The official added that to support his application, Rocky also submitted a "renowned shooter" certificate issued by the National Rifle Association of India.
As far as residential address is concerned, the applicant is required to have resided there for at least six months and Rocky fitted the criteria, he added.
Rocky whose real name is Rakesh Ranjan Yadav is the son of ruling JD-U MLC Manorama Devi in Bihar. He allegedly shot dead 20-year-old Aditya Sachdeva for overtaking his vehicle and was arrested from his father's mixer plant in Gaya district on Tuesday.
Police also recovered the Beretta pistol which was used in the crime.
