"The repeated increase in the petrol prices indicates that the Congress-led central government doesn't care about the aam aadmi' (common man)," said SP spokesperson in the state, Rajendra Chaudhary.
Protesters shouted slogans against the Congress government and took the protest march in front of the state assembly.
"It's not the case of petrol only, the United Progressive Alliance has miserably failed to contain prices of other commodities too. The government has not done anything substantial that could provide relief to the public from the ever-rising inflation," added Chaudhary.
The Bharatiya Janata Party (BJP) also staged demonstrations in various parts of the state capital against the hike in petrol price.
Earlier, on Thursday midnight, Sept 15 the petrol prices were increased by Rs 3.14 per litre.
