Bhola Nath Mullik, popularly referred to as B.N. Mullik, was commissioned in the imperial Indian Police, with initial posting in Bihar. He would later become the second and long-serving Director of post-partition India's Intelligence Bureau (IB). He hailed from Calcutta, Bengal.
He was a fierce loyalist to Prime Minister Jawaharlal Nehru and point-person for major foreign policy as well as internal political issues. He was deemed a 'colossus' by contemporaries in the police.
Some observers noted that Mullik relied on 'extra-sensory perception' more than informed intelligence assessments when advising Nehru, especially on matters pertaining to China.

Miscellaneous:-
It was on Mullik's advice that Nehru directed the establishment of Special Frontier Force (SFF), a paramilitary force to counter Chinese military forces
Mullik was referred to as 'g*d' by the junior officers, and some had great regard and admiration for him. Many others hated him equally
Mullik was probably the most extensively travelled DIB. He visited a large number of check posts along the Indo-Tibetan border. Mullik was, therefore, up-to-date and well informed on border affairs
He had plans to set up an 'Assamese Resistance Force' along the lines of SFF in India's northeast
