The Bombay High Court on Wednesday asked Elgar Parishad-Koregaon Bhima case accused Vernon Gonsalves to explain why he kept "objectionable material" like a copy of Leo Tolstoy's "War and Peace" and some CDs at his home. Justice Sarang Kotwal, hearing the bail plea of Mr Gonsalves and others, also said that "such books" and CDs indicated they contained some material against the nation.
