The probe into "objectionable" CD, which surfaced on Thursday showing Kumar in a compromising position with a woman, has been given to Crime Branch on the order of commissioner of police, sources in the Delhi Police said.
A delegation of Delhi BJP Friday met Kumar and lodged a complaint against the sacked AAP minister, Chief Minister Arvind Kejriwal and Deputy CM Manish Sisodia, accusing them of "misusing their public authority against women".
The complainants, including BJP MP Parvesh Verma, Manjinder Singh Sirsa and other party leaders met Kumar at the Police Head Quarters and urged him to register an FIR against Sandieep Kumar.
The BJP leaders also demanded "legal action" against Kejriwal and his deputy Sisodia for "protecting" Sandeep.
In separate complaints lodged with Anti Corruption Branch(ACB), RTI activist Vivek Garg and BJP MLA OP Sharma have demanded a probe against Sandeep.
The decision to remove Sandeep from the Cabinet was taken at a high-level meeting attended by top AAP leaders last night.
He, however, today alleged he was being targeted under a "conspiracy" as he was a Dalit and demanded a probe into the issue.
