The Mumbai Police have confirmed that a non-bailable warrant (NBW) has been issued against Maharashtra Navnirman Sena chief Raj Thackeray and he might be arrested. However, the warrant against Raj is not for the attack on outstation candidates on Sunday, it was issued for a speech made by Raj in February where he had spoken against north Indians and had also targetted Amitabh Bachchan in that speech.
