"They (National Democratic Alliance) should first explain as to how he (Rocky) got license for his pistol in Delhi without verification," he told reporters at PatnaAirport while returning from Delhi.
The Delhi police is under the Centre hence they need to explain about the issuance of license in violation of rules, the Rashtriya Janata Dal leader said.
"We demand a probe into the license issued to Rocky without proper procedure of verification," he said in a strong counter-offensive against BJP which had gone hammer and tongs against the Bihar government over the murder of Aditya Sachdeva on Saturday last by Rocky in a road rage incident.
The Gaya police maintained that the pistol license to Rocky Yadav had been issued from Vasant Kunj area of Delhi. The Bihar Deputy CM also said the fugitive member of Legislative Council and mother of the accused would be arrested.
He said RJD workers met the aggrieved family of standard XII student Aditya Sachdeva who died after being allegedly shot at by Rakesh Ranjan Yadav alias Rocky Yadav for overtaking his SUV.
Tejaswi Yadav, the son of RJD chief Lalu Prasad Yadav, had commented two days back in Delhi as to why the term "jungle raj" was not referred to incidents like Pathankot attack, large number of road rage cases in Delhi and killing of an officer in Jharkhand.
The comment drew sharp reaction from his political rivals who took exception of him bringing up the Pathankot terror attack issue while referring to the audacious Gaya road rage case.
In another broadside at the Bharatiya Janata Party, Tejaswi also wondered "why the BJP is not talking about 'jungle raj' (regarding) what they did in Uttarakhand?"
