The Congress leaders were accompanied by around 150 supporters who tried to storm into the railway station, when they were stopped by the police.
Delhi Congress leaders Arvinder Singh Lovely, Sajjan Kumar and Mukesh Sharma were detained by the Delhi police at the Nangloi railway station today, as they tried to block trains there in protest against the water and power crisis in the capital.
The Congress leaders were accompanied by around 150 supporters who tried to storm into the railway station, when they were stopped by the police. Water cannons were also used to control the crowd.
"Under our rule of 15 years, Delhi never saw a power crisis. This is unacceptable and we demand immediate relief for the people," Mr Lovely had said on Thursday during the protest.
The Congress has been agitating against the erratic power and water supply in different parts of the capital for the last few days.
Following a storm May 30, which damaged transmission lines in Delhi, the city has seen erratic and long power cuts in sweltering heat.
