Her medical status report, in a sealed envelope, has been sent to the Esplanade Court which sent her -- along with the two other main accused, her ex-husband Sanjeev Khanna and her former driver Shyamwar Rai -- to judicial custody till October 19.

Through her lawyer Gunjn Mangala, Indrani expressed her readiness to be interrogated by the Central Bureau of Investigation (CBI) in jail.
