The Patidar quota agitation leader Hardik Patel has threatened to intensify the agitation if the arrested youth were not released immediately.
The Surat Police chief said some people at the venue had pelted stones at the police, PTI reported.
A mob set two buses and three motorbikes afire to protest the detention of a few members of the Patidar community in Surat on Tuesday night, the eve of Japanese prime minister Shinzo Abe's two-day visit to Gujarat. The situation was brought under control by police soon after the PAAS supporters and Patidar residents of the area have allegedly joined in the violence. "Luckily, no one was injured. The situation is now under control in Kapodra area as well as rest of the city", Sharma was quoted as saying.
He also claimed that the protest was peaceful but the police used lathi-charge for no reason. He also asked the police to not allow any event in Patel-dominated areas of the city. "If the youth aren't released at the earliest, then Gujarat will witness a revolution", Patel said in a tweet posted in Gujarati.
The violence in Surat triggered agitations in Ahmedabad, where some youth began to shout slogans on the ongoing Patel agitation demanding reservation in government jobs. They forced the passengers to get down and later torched the buses.
Surat has over 1 million population of Patels also known as Patidars.
President of Gujarat BJP youth wing Rutvij Patel said the "ruckus was created by 6 to 7 persons" and that the incident did not reflect the sentiment of the entire Patel community.
