BENGALURU: Cops are seeking to chargesheet Mehdi Masroor Biswas, 26, the alleged operator of a pro-ISIS Twitter handle. But they are yet to hear from Google on their request to access his three Google accounts.

About a month ago, a request was made to Google seeking access to the accounts but there's been no word yet from the company.

Although hacking into these accounts is an option for cops, they are wary as it would leave hash values (e-footprints) in the account and could be considered tampering with evidence. Cops want to go by the book and access the accounts only through the service provider.

It was recently revealed that a youth from Hyderabad who was arrested for his association with ISIS was in touch with Mehdi. Police are looking for more such possible recruits.

"Once we access these Google accounts, we can find more evidences, especially of any personal communications he had with pro-ISIS supporters or even fighters," said sources.

However, officers said the recent busting of the IM explosive supply module and Church Street blast case have taken their attention away from this case. Many officers who were investigating Mehdi case have been assigned to the special investigation team probing the blast.

Police have already found over 12,000 direct messages sent on his Twitter account, with the help of Twitter India, which they claim have given them solid evidence to prove Mehdi's role in inspiring youths to be part of ISIS/ISIL.

Sources said NIA investigators weren't too interested in Mehdi and didn't spend much time questioning him. Neither is the NIA in any mood to taken over the investigation.

There have been some apprehensions raised about the charges filed against Mehdi, but the city police commissioner is firm that the evidence collected during the investigation substantiates these charges.

Sources said the chargesheet in this case will not be filed anytime soon and cops would utilize three months' time to file it.
