The STF had announced a reward of Rs 3,000 against Shivhare, who was posted as Deputy Inspector General (DIG) but absconded after the probe agency registered a case against him and directed him to appear before it.
Later, he was suspended and was evading summons.
Shivhare is an accused in pre-post graduate exam for post-graduate courses in the medical stream in which his daughter and son-in-law (both medical students) were already named as accused, police sources said.
STF officials are questioning Shivhare on the issue and will produce him in a court tomorrow, sources said.
