Kolkata doctor rape-murder case: CBI conducts polygraph test on Sandip Ghosh

The CBI conducted a polygraph test on Sandip Ghosh after determining his responses to be inconsistent over a nine-day investigation. Ghosh faced inconsistencies regarding events on August 8 and 9, including his absence when police arrived at the hospital. This follows his Layered Voice Analysis (LVA) test. Several doctors also underwent polygraph tests again on Monday.
