A day after Congress leaders were detained when they tried to obstruct the movement of trains at Nangloi railway station in west Delhi, the party's senior leaders Ajay Maken, Shakeel Ahmed and Arvinder Singh Lovely protested in central Delhi's Karol Bagh area.
Scores of party workers, joined by locals, shouted anti-BJP and anti-AAP slogans.
"If the crisis is not resolved soon, we will cut the electricity supply to the houses of Manish Sisodia (Aam Aadmi Party leader) and BJP leaders," Delhi Congress chief spokesperson Mukesh Sharma said here.
The national capital has been reeling under long hours of power cuts, following a May 30 storm, which damaged transmission lines.
The Congress - out of power both at the centre and in Delhi - has held a string of protests over the outages. President Pranab Mukherjee's daughter Sharmistha joined one such protest Saturday.
Congress general secretary Ajay Maken blamed Delhi's former chief minister Arvind Kejriwal and Prime Minister Narendra Modi for the power crisis in the capital.
"Arvind Kejriwal and Narendra Modi are responsible for this condition of Delhi. Arvind Kejriwal wanted to be seen on television, so he protested at Rajghat," Maken said.
"I want to ask Piyush Goyal (union power minister) that last year approximately 5,800 MW electricity was supplied in Delhi, then why you are not able to fulfil the requirement of just 5,600 MW," he added.
