The Central Bureau of Investigation (CBI) arrests Giribala Singh, the mother-in-law of Twisha Sharma, in connection with the high-profile case involving Sharma. NDTV and other outlets report that Singh is taken into CBI custody after earlier police remand ends, with CBI weighing the next step of judicial custody. India Today and The Economic Times also state that Singh is arrested by the CBI. India Today further reports that Twisha Sharma’s husband and mother-in-law are sent to five days of CBI custody, indicating the investigation is ongoing and involving multiple family members. NDTV notes that security concerns are considered as the police remand period concludes, and that CBI’s custody decisions are being made in the immediate aftermath of remand expiry. While details of the allegations and the timeline of prior arrests are not provided in the supplied excerpts, all reports agree on the core development: Giribala Singh is arrested by the CBI and custody—first with the CBI and then potentially in court—becomes the focus as remand ends.
