Carrying out searches in three houses of Kohli, the police today also seized four printers, pen drives, marriage CD, marriage cards, registers and other things, police said.
Kohli, along with his mother, was arrested in Delhi on the night of August 26 following allegations by his newly married wife Tara Shahdeo, a national level rifle shooter.
She had also claimed that Kohli had hidden that he had converted to Islam and that she was forced to except his religion. Kohli had denied the charges.
Meanwhile, former state Assembly Speaker Inder Singh Namdhari admitted at a press confernce that he had sought Kohli's help in legal matters.
Namdhari who attended the wedding of Tara Kohli on July 7, said he had asked him to engage advocates to get a murder convict released on parole as the convict's ailing daughter needed operation.
"When the Chatra based family of a BJP leader, who was convicted in a murder case and got life imprisonment, approached me to help him get interim bail to get his daughter treated, I entrusted the responsibility to Kohli, whom I was introduced to, a year ago," Namdhari said.
"Even I told Tara Shahdeo on their wedding day that I had come only because Kohli had helped me obtain bail for that person," the ex-speaker said.
"But who knew such events would unfold within one-and-a-half months of their marriage," he added.
Today is the last day of the three-day police remand of Kohli. A Chief Judicial Magistrate had earlier sent him to 14 days judicial custody on August 28. His mother is in judicial custody.
Chief Minister Hemant Soren has said the government would recommend for a CBI probe into the case.
