Bangalore, Feb. 14: V.K. Sasikala is no stranger to the central jail in Bangalore.

In 2014, Sasikala, then Tamil Nadu chief minister Jayalalithaa, Sasikala's nephew V.N. Sudhakaran and sister-in-law Ilavarasi had spent 21 days in Parappana Agrahara Central Jail, 20km from the city, in the disproportionate assets case in which the conviction was upheld today by the Supreme Court.

Justice Michael D'Cunha of a special court in Karnataka had then sent the four to four years in jail in October 2014 in the case.

As the special court was dismantled after the case was heard, Karnataka High Court today appointed sessions judge Ashwath Narayana as the judge-in-charge of the court where Sasikala and the others would surrender.

"The (Supreme Court) judgment says clearly that the three of them would have to surrender forthwith at the special court, which means by 5.30pm when the court closes for the day," senior Bangalore-based lawyer G.R. Mohan, who is not linked to the case, said.

The surrender can, however, be formalised at the judge's residence any time of the day or night. "Judges have powers round the clock," Mohan said.

Soon after the Supreme Court verdict convicting Sasikala, Sudhakaran and Ilavarasi on an appeal filed by the state of Karnataka, Bangalore police threw a security ring near the central jail entry.

Reacting to the verdict, state law minister T.B. Jayachandra said: "We had built a very good case. We will get a clear picture of our responsibilities once we get a signed copy of the order."

Several personnel have been deployed to keep vigil although the jail authorities are yet to get any information on when the trio would arrive. In October 2014, thousands of AIADMK workers from Tamil Nadu had gathered in front of the jail, creating a security nightmare for the local police.

A police source said there was no information on when Sasikala and the others would be produced for surrender before the judge, but the state police were in touch with their Tamil Nadu counterparts as Karnataka cops would take charge of them once they cross the border in Hosur, 30km from the prison complex.

"It's (bringing the trio to the jail) not possible now since the prison is already<> closed for the day," a source said. The jail closes at 6 every evening. "The order passed by the judge after the surrender is the only document needed for the jail authorities to admit them," a police source said.

Once the entries are made, the prisoners will undergo mandatory medical examinations before being shifted to their cells.

In 2014, Sudhakaran had complained of uneasiness and had been admitted to the prison hospital. Jayalalithaa, who had maintained a stoic silence for the first two days, had adjusted to her private cell quickly, prison sources had said then.

A source said it was unlikely that Sasikala, Sudhakaran and Ilavarasi would get any special treatment in the prison going by their profile. Jayalalithaa was a VVIP and so had to be kept separately from the others. She had been given some facilities like a fan and newspapers in English and Tamil.

Other inmates of the VIP cells of the jail have been former Karnataka chief minister and BJP leader B.S. Yeddyurappa and his ex-cabinet colleagues Gali Janardhan Reddy and Krishniah Setty, who had spent more than 20 days in October 2011 over a Lokayukta report on illegal mining.
