Highly-placed sources said that while circumstantial evidence and the statement of Yahya suggested involvement of three more players, nabbing the suspects was required before proceeding further in the probe.
The sources said that the wanted persons by the Delhi Police were bookies as well as punters who were contacts of three cricket players against whom evidence was being gathered.
"We will be progressing against three more players only after we are able to nab those named by Yahya during his questioning to get direct evidence," a senior official associated with the probe said.
Delhi Police has arrested 19 people including three cricketers of Rajasthan Royals -- S Sreesanth, Ankit Chavan and Ajit Chandila.
Chavan was sent to judicial custody till June 4 after police told the court that he was not required for any further questioning by it.
