She was presented before a court today which extended her remand till August 12.
Additional SP Shailendra Singh told PTI that a laptop, pen-drive and some other electronic gadgets had been recovered from Arora's residence in Mumbai but a mobile phone, which was allegedly used to blackmail the deceased, had not been found as yet.
He said that the accused kept changing her mobile number and used to record her conversations with Yagnik.
Arora is accused of demanding Rs 5 crore from Yagnik and threatening to frame him in a false case if he failed to pay up.
Police said that she was miffed with Yagnik after being sacked from the newspaper and allegedly blackmailed him in order to get reinstated.
Yagnik had allegedly committed suicide on July 12 by jumping off the three-storey building on AB Road that houses the newspaper's office.
Arora was booked on the charges of abetment of suicide, extortion by putting a person in fear and relevant sections of the Information Technology Act.
