VHP leaders, former councillors and chief of panchayats were among 50 people booked for violence during a protest that was held here last week demanding the demolition of an illegal portion of a mosque in the Sanjauli area, police said on Sunday.

Protesters clashed with security personnel on September 11, breaking barricades and pelting stones as police used water cannons and batons to disperse them. About 10 people, including police and women, were injured.
