Chandigarh Police used tear gas and water cannons on Saturday to prevent Qaumi Insaaf Morcha supporters from entering Chandigarh at the Mohali border.
Protesters attempted to breach police barricades using tractors to demand the release of Sikh prisoners, leading to a heavy deployment of security personnel.
The organization has announced a 'Punjab Bandh' for August 21 to continue their protest and press for the release of the prisoners.
