How did subject experts sneak NEET 2026 questions out of NTA's confidential wing?

According to CBI, NTA Chemistry expert PV Kulkarni used plain sheets meant for rough translation work to make small chits and write 135 questions with their answer options. Biology expert Manisha Mandhare and Physics expert Manisha Havaldar allegedly memorised questions. They were not frisked before exiting NTA's Delhi office's 'confidential wing', which also lacked adequate CCTV monitoring.
