The Punjab Police used water cannons and cane-charged Youth Congress activists, including women, who were heading towards the new terminal of the Chandigarh airport demanding that the airport be named after freedom fighter Bhagat Singh.
A number of activists were injured in the police action.
Police stopped the activists at a barricade put up on the way to the new airport terminal, located on the Mohali side in Punjab.
As the Youth Congress activists tried to break through the security cordon, police used water cannons and cane-charge to disperse them.
The Youth Congress had started a 'Padyatra' on Monday from Khatkar Kalan, the native village of Bhaghat Singh, located 80 km from here, in Punjab.
The airport terminal has not yet been given a name nearly four months after being inaugurated by Prime Minister Narendra Modi in September last year.
Punjab and Haryana, which have 24.5 percent stake each in the airport terminal project, had agreed long ago that it should be named as 'Shaheed Bhagat Singh International Airport'.
The Punjab and Haryana assemblies had, in 2009 and 2010, respectively, passed resolutions for naming the airport after Bhagat Singh.
