The PIL, filed by Ratna Vora, an advocate associated with NGO Ambedkar Karwan, is likely to come up for hearing on Wednesday.
Demanding investigation by the central agency, the petitioner contended that current probe into the incident by CID may remain "inconclusive" like in the Thangadh case wherein three Dalit youths were allegedly killed in firing by police in 2012 in Surendranagar district.
The PIL stated that CID had submitted a closure report in the Thangadh case saying no offence was made out against anyone. Police have not yet filed any charge sheet in the case.
Police have arrested over 30 people in connection with the assault on Dalits.
