Additional Sessions Judge S B Kachare extended the judicial custody of former police inspector of Pune Rural Police Bhausaheb Andhalkar and his then subordinate Namdev Kauthale by 14 days.
Lawyers of both the accused also filed bail applications.
"Hearing on bail applications will take place on May 12," said advocate Sudhir Shah who is representing Andhalkar.
CBI, which is investigating the case, arrested the two former police officers for allegedly conspiring with others and fabricating and manipulating evidence to shield the real culprits.
Shetty, through RTI queries, had unearthed some land scams in the district.
In August 2014, CBI filed a closure report saying it could not find any evidence against the suspects. But in early 2015, it reopened the case in view of some new evidence recovered during searches in Pune and Mumbai.
