Over 500 Shiv Sena activists have been booked on charges of violating prohibitory orders and attempts to incite communal tension in the city, police said on Tuesday.

The Sena activists had Sunday taken out a procession in areas where Section 144 of the CrPC was in effect and raised 'objectionable' slogans, police said.

They have been booked under section 153 A (promoting enmity between different groups) of the IPC and for violating prohibitory orders.

The authorities have imposed Section 144 in the district in view of the upcoming panchayat polls.
