Superintendent of Police Mukesh Singh told PTI that three persons were arrested last night from the 7th Mile area while they were trying to burn tyres on NH 44.
Police also recovered one bottle of petrol along with six tyres from their possession.
The road blockade in Jaintia Hills district which began last night was called by seven student and youth organisations demanding immediate and unconditional release of five leaders of Jaintia Youth Federation (JYF), who were arrested on charges of looting and ransacking shops.
Sources said vehicle tyres were burnt at different places in the district last night, even as the blockade call did not evoke much response.
The organisations alleged that the five arrested JYF leaders were being framed.
