Five persons had died on election day in Sitalkuchi.
Dhankhar, whose visit to Cooch Behar was roundly criticised by Chief Minister Mamata Banerjee, was shown black flags by some people at Golokganj as his convoy travelled from Mathabhanga to Sitalkuchi though a posse of policemen put up a human wall to prevent protesters from coming down on the road.
Posters and placards criticising the visit of the governor were also seen at Jorpatki, the scene of firing by central armed police force (CAPF) that killed four persons on April 10 during the fourth phase polling.
A first time voter was also killed at Sitalkuchi while waiting outside a polling booth to exercise his franchise.
