Talking to one of the advocates after his hearing in a Bengaluru court on Thursday, Islamic State's Twitter account handler Mehdi Masroor Biswas said he had no regrets about what he did.

When one of the advocates present during Biswas' hearing at Bengaluru's Civil Court Complex asked: "Why did you do this, man?" Mehdi replied saying: "I'm a soldier and messenger. I don't regret what I've done," The Times of India reported.

The brief conversation between the advocate and ISIS twitter account @ShamiWitness' handler Biswas happened on the day he was produced before the court last week.

The team of Bengaluru police, headed by Central Crime Branch ACP Thammaiah, sought 25-day custody of Mehdi to investigate the case further. The police said they might need to travel to others states and countries for checking thousands of tweets on his account.

However, the judge, Somaraju, denied permission to take him outside India and granted a 15-day custody, posting the next hearing on 2 January at 3 pm.

"Police say they need more information from you and have sought 25 days of custody. I'm handing you to police custody for 15 days, and they will bring you to this hall on January 2 afternoon," Somaraju told Mehdi.

"Only in case of emergency and based on requirement, will police custody be extended further," he added.

Biswas was arrested last week for allegedly handling ISIS' top twitter account, which has 17,700 followers. He was booked under Section 66F of Information Technology Act 2000, for "cyber terrorism".

The report about his alleged involvement with ISIS was revealed by UK-based Channel 4 News on 10 December.
