The SP sustained injuries on her hand while trying to save a BJP worker during the clash which occurred when the party activists attempted to show black flags to Odisha Food Supplies and Consumer Welfare Minister Sanjay Dasburma, police said.
The incident took place a day after many BJP activists were allegedly thrashed by BJD workers while showing black flags to Dasburma and Housing and Urban Development Minister Pushpendra Singhdeo at Manamunda in Boudh district.
Though, apprehending trouble during the minister's visit to Angul, police had earlier detained about 10 senior BJP leaders, another group marched towards the circuit house and waved black flag at Dasburma.
A BJP delegation, led by the party's newly-appointed Legislature Party leader K V Singhdeo visited Manmunda, where BJP organised a 12-hour bandh.
BJD spokesperson Samir Ranjan Dash said today's clash was a "spontaneous reaction" as BJP workers obstructed Dasburma from participating in a demonstration against Chhattisgarh government over construction of a string of barrages on Mahanadi river.
