"Another riot took place in 1874 of which there is an eye-witness account by the great Indian leader Pherozeshah Mehta.67*. In a book written by a Parsi vaccinator there was a reference to the Prophet which was regarded as objectionable by the Muslims. The publication was accordingly suppressed by the Government and the author was made to apologize for any affront he might have inadvertently offered. Nevertheless, there was “a brutal and unwarranted attack on Parsis by a mob of Mohamedans”, on 13 February, 1874. They “invaded Parsi places of worship, tore up the prayer- books, extinguished the sacred fires and subjected the fire-temples to various indignities. Parsis were attacked in the streets and in their houses and free fights took place all over the city. Thanks to the weakness and supineness of the police and the Government, hooliganism had full play and considerable loss of life and damage to property were caused”. The riot continued for several days till the military was called out. Pherozeshah Mehta, like Dadabhai Naoroji, none of whom one would accuse of having any special animosity against the Muslims or the British Government, has laid emphasis on the callousness of the police and the indifference of the Government. “The attitude of the Commissioner of Police was particularly hostile and objectionable. The Governor told a Parsi deputation that waited on him that the conduct of the community had been injudicious and unconciliatory and advised it to make its peace with the Muhammadans and to learn the lesson of defending itself without dependence on the authorities.”"
