Congress units of Haryana and Punjab on Monday held protests against the Enforcement Directorate's summons to their leader Rahul Gandhi in a money-laundering probe and accused the Centre of misusing investigative agencies to ''suppress'' the opposition.

Police briefly detained several Haryana Congress MLAs and workers when they tried to take out a protest march to the ED office here in support of their leader Rahul Gandhi, who appeared before the probe agency in Delhi.  

The party's Punjab unit, led by its chief Amrinder Singh Raja Warring, also held a protest near the ED office in Jalandhar.

The Congress will continue to fight against the BJP's ''dictatorial and vindictive politics'', Warring said. 

In Chandigarh, Congress legislators Raghuvir Singh Kadian, Geeta Bhukkal, Varun Chaudhary, Jagbir Malik, and Aftab Ahmed among others, led by Haryana Congress chief Udai Bhan, gathered at the party's state headquarters in Sector 9 to take out a protest march. However, the police had put up multi-layered barricades close to the Congress' office and packed the leaders in two buses when they tried to march towards the ED office in Sector 18. They were taken to the Sector 3 police station and were let off after being briefly detained. Bhan accused the BJP-led government at the Centre of misusing central probe agencies to ''suppress the voice of the opposition''.

In Jalandhar, Warring said the Congress party will continue to fight against the BJP's dictatorial and vindictive politics. ''We are proud that we are members of that party whose history is full of sacrifices for the sake of this country,'' he said, adding that the Gandhi family too had ''made supreme sacrifices for the nation''. He also alleged that the Aam Aadmi Party is the BJP's ''B team''.
