The two-hour disruption of Metro services between Vaishali and Yamuna Bank stations on Saturday spelled trouble for thousands of passengers.
Metro services between the stations were suspended after protesters pelted stones at a banquet hall below the Karkardooma Metro station and set it on fire.
The Delhi Metro Rail Corporation shut down its line No. 4 from 4.20pm to 6.20pm keeping in mind the security of passengers and trains.
Some passengers complained that they were given no information by Metro authorities. "There was no information on why the Metro services had been shut down and when they would resume," Vaishali resident Sharad Singh said.
The shutdown meant switching to other modes of transport for many passengers, including Singh.
"There was a lot of confusion at the Vaishali Metro station when I went there at 4.30pm. I had to hire an auto-rickshaw to Anand Vihar, hoping to board a train from the station there. But it was closed, too," he said. "So, I hired another auto-rickshaw to Connaught Place at an exorbitant fare."
Others, however, had to walk several kilometres to find buses or auto-rickshaws.
"I was riding a rickshaw to the station in Karkardooma around 5.30pm when I was stopped by policeman. I decided to walk till the station and found a rush of passengers there waiting to go in," Rashmi Singh, a resident of Jhilmil colony, said.
"There was also smoke coming out from a building at the station. I started walking to the Preet Vihar Metro station but the station was closed there too. After walking another kilometre, I found an auto-rickshaw," she added.
Even after the Metro services resumed, trains did not stop at the Karkardooma station. "At 6.20 pm, the services resumed but trains did not stop at the Karkardooma Metro station," a DMRC spokesperson said.
