Waseem Pathan was picked up from Mumbai, where he was hiding, on Wednesday night and brought to Hubballi this morning, police sources said.
Video footage purportedly showed Pathan standing on a police official's jeep and addressing a crowd of people gathered outside the old Hubballi police station to protest against the alleged post, showing a saffron flag planted on a mosque, that surfaced on social media on Saturday night.
After the speech, the mob went on a rampage damaging many police vehicles, and hurled stones at a nearby hospital and temple.
After the police named him in the FIR, the cleric went into hiding and released a video on social media claiming that he was innocent.
