Subhash Chandra Bose decided to take revenge, after reading so many incidents about the exploitation of the fellow Indians by the British. In 1916, Subhash reportedly beat and thrashed one of his British teachers E F Otten. The professor made a racist remark against the Indian students. As a result, Subhash Chandra Bose was expelled from the Presidency College and banished from Calcutta University. The incident brought Subhash in the list of rebel-Indians. In December 1921, Bose was arrested and imprisoned for organizing a boycott of the celebrations to mark the Prince of Wales's visit to India.
