A case was registered last evening at the Civil Lines police station here against Baghel, Verma and others under section 67 (A) of the Information Technology Act following the minister's complaint, Station House Officer (SHO), Civil Lines, Hem Prakash Nayak told PTI.
"A copy of the CD has been submitted to the police station and it will be sent for forensic examination," he said.
Munat, considered close to Chief Minister Raman Singh, was accompanied by state BJP president Dharam Lal Kaushik, his over half-a-dozen cabinet colleagues and other party leaders, while filing the complaint.
Talking to reporters yesterday, Munat had alleged that the CD in question was fake and urged the chief minister to order a probe to find the truth.
"The (sex) CD is fake. It is an attempt to malign my image," he had said.
The minister further appealed to the chief minister and Kaushik to get the matter investigated from any agency.
Yesterday, the Civil Line police had also arrested two AAP supporters for allegedly blackening Munat's nameplate while protesting outside his official residence over the row.
Police also claimed to have recovered 500 "porn" CDs, a pen drive and a laptop from Verma.
A Ghaziabad court had granted the Chhattisgarh Police the transit remand of Verma till October 30 and he is expected to reach Raipur this afternoon.
