The sprawling in Mumbai’s Worli neighbourhood owned by Indrani and Peter Mukerjea, was among one of the places raided today to determine whether the duo, which owned INX Media, colluded with former finance minister P Chidambaram to allegedly bring in illegal amounts of foreign investment in 2007.

Indrani and Peter Mukerjea have both been in jail since 2015 on charges of murdering Sheena Bora, who was Indrani’s daughter from her first marriage.

According to a NDTV report, the Central Bureau of Investigation, which is investigating the investment approval given Chidambaram, is also handling the murder case. It is believed that some information about Chidambaram’s son, Karti’s alleged criminal misconduct was gained from the murder investigation.

Meanwhile, Chidambaram has denied any wrongdoing and described the raids as a witch hunt.

The CBI had said in court that it was collecting details of a Singapore bank account opened in Sheena Bora’s name and whether and how funds were transferred there before she was killed. ¬†According to the reports, the investigators haven’t ruled out the financial motive to the 23-year-old’s killing. In 2009, the Mukerjeas sold their media business amid charges of embezzling funds.

In its case or FIR, the CBI alleges that as Finance Minister, Chidambaram allowed the Mukerjeas to get foreign investment of 305 crores, though the Foreign Investment Promotion Board (FIPB) had sanctioned only four crores.

Sheena Bora’s murder was discovered in 2015, three years after Indrani Mukerjea told friends and family that she had moved to America. Through her life, Sheena Bora was presented by Indrani Mukerjea as a sister.

Sheena Bora in 2012 was allegedly strangled by Indrani Mukerjea, her driver and her first husband. Investigators say the body was kept overnight in the car at “Marlow”, the mansion that was raided today.

Peter Mukerjea knew of the conspiracy, investigators have said. His wife and he have pleaded not guilty.
