Hakim alleged that the Bihar Chief Minister's move was for instigation before the general elections.
"We condemn this " Hakim said.
Kumar yesterday directed IGP Special Branch G S Gangwar to meet police officers in Kolkata to find out details of the case and submit a report to the Bihar government.
The 16 year-old victim, the daughter of a taxi driver, was gang-raped in October last year and again when she was returning after lodging a police complaint.
She died in hospital three days ago due to burn injuries after she was allegedly set ablaze.
