Police in Hyderabad, Adilabad and Nizamabad districts, during the last two days, registered three cases against Owaisi for allegedly making hate speeches last month.
The courts in Hyderabad and neighboring Ranga Reddy district directed the police to book Owaisi under Section 153 (A) of the Indian Penal Code for promoting enmity between different groups.
However, the police in Nirmal town of Adilabad district went a step further and registered a case under Section 121 (waging or attempting to wage war against the state).
Police in Nizamabad also booked the MIM legislator under Section 295 A (for deliberate and malicious acts intended to outrage religious feelings).
The police Friday served notice to Owaisi, who is away in London for treatment, summoning him for questioning at Nirmal police station on Jan 8 and at Nizamabad on Jan 9.
The 42-year-old firebrand, younger brother of MIM chief and Member of Parliament Asaduddin Owaisi, faces arrest in the case.
