"Unko kahiye ki aur khulashe karen taki unlogon ke khilaf karwai ho sake (Ask Singh to reveal more so that action can be taken against those persons)," a bench comprising Chief Justice T S Thakur and justices R Banumathi and U U Lalit said.
The bench dismissed the plea filed by Ramesh Ranchhoddas Joshi, a native of Mumbai, seeking a comprehensive probe into the claims of Raj Kumar Singh, former bureaucrat lawmaker who had also served as Home Secretary during UPA rule.
The MP had claimed that many policemen were getting money from Dawood and in the process, were undermining the law and order of the country, he said.
The CJI responded in Hindi and later, dismissed the plea.
