The protesters refused to allow the hapless students a safe passage along the foreshore road even when the latter begged and showed their admit cards.
The students who missed the opportunity to appear in the CET had their examination centres inside Kashmir University and Regional Engineering College in the city.
The protesters were demanding free access to building material for houses around the lake and no restriction on constructions in the area.
Similarly, tourists were unable to visit the famous Mughal Gardens around the lake due to the protests held against Lakes and Waterways Development Authority (LAWDA), which is responsible for the preservation of the Dal Lake and its eco-system.
Acting on State High Court directions, LAWDA had disallowed taking away of building material from around the water body and also dismantled illegal constructions posing a direct threat to the delicate ecology of the Dal Lake.
The residents of areas around the Dal Lake forced shut all markets outside the Mughal Gardens. The area wore a deserted look due to absence of tourist inflow on Saturday.
