Karti was produced on expiry of his three-day police remand before special judge Sunil Rana who sent him to Tihar Jail, after the CBI, in whose custody he was quizzed continuously for 12 days since his arrest on February 28 from Chennai, said he was no longer required for further custodial interrogation.

"In view of the fact that no more police custody remand of accused is sought by CBI, accused Karti Chidambaram is remanded to judicial custody. He be produced on March 24," the special judge said.

The court, which refused Karti's plea for a separate cell in the jail in view of threat perception as during his father's tenure as Union Home Minister several terrorists were kept in Tihar jail, said the social status of the Chidambaram family cannot be ignored but he cannot be treated differently from the other accused persons.

"The apprehension raised by the senior counsel for accused cannot be ignored keeping in view the social status of accused and his family, more specifically, his father, who is a former union minister. "However, only keeping in view the fact of social status of accused and his father, he cannot be treated different from other accused persons and cannot be allowed to be kept in separate prison. However, lock up in-charge and jail superintendent are directed to provide and ensure proper security and safety to accused during judicial custody, as per rules," the court said.

Meanwhile Karti alleges 'inhuman treatment' in CBI custody

The accusations were made by Karti when he was produced before special judge Sunil Rana who directed the CBI sleuths to "do the needful, as per rules".

The Delhi High Court stopped Karti Chidambaram's counsel from making any remarks on Indrani Mukerjea, former director of INX Media who is in jail in connection with the killing of her daughter Sheena Bora.

A bench of justices S Muralidhar and I S Mehta told Karti's counsel "Don't go into all this" when he asked how could investigating agencies, the CBI and the ED, even rely on the statement of Mukherjea who herself is in jail in connection with her daughter's killing.

CBI to file its reply on bail plea of Karti Chidambaram, son of former Finance Minister P. Chidambaram on March 14 in connection with the INX media money laundering case.

The CBI has moved a plea for custody of Karti's chartered accountant S Bhaskararaman for confrontation between the two and has also filed another application seeking permissions to produce Indrani and Peter Mukerjea for confrontation and identification of some locations in Delhi.

Meanwhile, Karti 's counsel Abhishek Manu Singhvi told media, "We had two matters today. One was the ED matter, court has given protection till 20th March. Our bail application is now listed for March 15.

Even as it gave an interim relief to Karti Chidambaram, the Delhi High Court extended until March 22 the judicial custody of his chartered accountant, S Bhaskararaman, who had been arrested by the Enforcement Directorate in the INX Media case.

Karti's CA had sought bail, saying he was not required for custodial inquiry. so there was no reason why he should be kept in custody.

Bhaskararaman had been imprisoned on February 26 after being quizzed by the Enforcement Directorate (ED), which had nabbed him on February 16 from a five-star hotel New Delhi.

The ED's special public prosecutor Nitesh Rana had earlier told the court that Karti's accountant had been assisting him to manage his "ill-gotten wealth" in India and abroad.

The Supreme Court on Thursday gave Karti Chidambaram the go-ahead to proceed to the Delhi High Court with his plea seeking an immunity against arrest.

Karti Chidambaram approached the SC requesting it to declare that the Enforcement Directorate had no jurisdiction to conduct any probe on matters not related to the allegations in the FIR filed by CBI on May 15, 2017.

The ED said allowing Karti Chidambaram, son of senior Congress leader P Chidambaram, to approach the high court in the money laundering case arising out of the INX Media graft case, would set a "bad precedent" for others.

The Vijay Rupani-led Gujarat government said that narco analysis Karti Chidambaram could be conducted at the Forensic Sciences Laboratory (FSL) in his state, provided the Modi government wished so.

Earlier, the CBI had approached a court in Delhi seeking a narco-analysis test on Karti to ascertain certain facts in the INX Media case.

Former finance minister P Chidambaram could also be called by CBI for questioning, several reports had said earlier, quoting officials of the investigating agency.

Earlier, the CBI had sought an extension of Karti's judicial custody in light of "new revelations". A further custodial interrogation was necessary to confront him with "new facts", it had said. Though there was a "substantial progress" in the INX Media case, the junior Chidambaram "had not been cooperating" and not disclosing passwords to his phones, the CBI had complained.

Also in other case the Supreme Court today rapped the Central Bureau Investigation (CBI) and the Enforcement Directorate (ED) for inordinate delay in completing the probe in 2G scam case. The Supreme Court directed the central agencies to complete the 2G scam probe in six months and submit report.

Coming down heavily on the agencies for delayed probe, the Supreme Court asked, "Are invisible hands stalling 2G probe?" It directed the agencies to report to the court interferences, if any, in 2G scam probe.

The Supreme Court's directive came during hearing of a contempt plea challenging the appointment of Tushar Mehta as the special public prosecutor in all 2G scam related cases. The apex court dismissed the contempt plea.

Meanwhile, the focus in the case has shifted onto former Union Finance Minister P Chidambaram in the case related to Aircel-Maxis deal. His role in giving FIPB (Foreign Investment Promotion Board) approval in Aircel-Maxis case is under the scanner.

Recently, the special trial court of Delhi acquitted all the accused including former Telecom Minister A Raja and DMK MP Kanimozli in 2G spectrum allocation case.

However, probe in other 2G scam cases are still going on. One of these cases involves P Chidambaram. In another case, his son Karti Chidambaram is facing probe and has been arrested by the agencies for another a different INX Media case and send to judicial custody.

Aircel-Maxis case was dismissed by the Patiala House court. It has been challenged by the CBI in the High Court. The case had been registered by the CBI in 2012-13 after the DMK had exited the UPA government following allegations against Dayanidhi Maran and his brother SUN TV chairman Kalanithi maran.

The CBI had then told the court that there were adverse remarks against Dayanidhi Maran in the Aircel-Maxis case.

Another critical question is, were kickbacks paid to Chidambaram for FIPB clearance?

There is an argument that the Aircel-Maxis case should have gone to the Cabinet Committee on Economic Affairs (CCEA) but it went to the FIPB and was decided by Chidambaram's ministry.

With the arrest of Karti more trouble is expected for Chidambaram family observe Law experts.
