Singh said numerous slips used to come from Home Minister's residence for posting and transfer in Delhi Police to the Police Commissioner.
“These were not a few postings but in large number of police stations,” he said.
“I don't know whether money used to exchange hands but Delhi Police Commissioner told me that numerous slips used to come from his residence... you don't make large number of recommendations... the postings as SHO's has a vigilance angle to it,” he said.
He claimed Delhi Police was stopped by Shinde from questioning a Mumbai-based businessman, who is said to have “some kind of links” with Dawood, in connection with the betting in Indian Premier League T-20 tournament.
The former Home Secretary said differences between him and Shinde were well known and even the Prime Minister also knew about it.
