Congress leader Hardik Patel was Monday detained by police after he threatened to sit on a hunger strike if the Gujarat government did not take action against Surat mayor and other officials over with the fire tragedy that claimed lives of 22 students, an official said.

The Congress had sought permission from the Sarthana police station here to hold a protest near the fire incident but it was denied. Despite that, Patel was on his way to the site, Surat Police Commissioner Satish Sharma said.
