Police officials in Nirmal and Nizamabad have already tested Akbaruddin's voice and taken samples to match his voice with that on the videotapes of his alleged hate speeches which the MIM leader has been accused of delivering at Nizamabad and Nirmal in December last year.
On February 5, the Nirmal police had got his voice recorded by Andhra Pradesh Forensic Science Laboratory (APFSL) experts, while his voice sample was recorded on February 12 in Nizamabad.
Voice samples in both the cases have been forwarded to the Central Forensic Science Laboratory (CFSL), Chandigarh.
The Nirmal and Nizamabad police have also questioned Akbaruddin in police custody, though he reportedly did not cooperate with the investigators.
