The country's first Public-Private-Partnership Metro project has had a tumultuous journey in the past 16 months after it first began operations in February, 2011.
"The Delhi Metro has received a communication from the concessionaire this evening that they intend to stop services from Sunday," Delhi Metro spokesman Anuj Dayal said.
However, he did not give any reason why the Reliance Infrastructure took the extreme step of closing down the Metro services for an unspecified period.
The Reliance Infra-led company has been suffering loses as it was not able to reach its intended targets in terms of profit and ridership. However, there was no word from the concessionaire.
Efforts made by PTI to reach Reliance Infra officials failed. It is understood that the company would come out with a public notice tomorrow, specifying reasons for its step.
Dayal said the Delhi Metro would be asking them to intimate the date by which they would be resuming services after carrying out the rectifications required on the line.

The high-speed Metro corridor, the country's first Public-Private-Partnership Metro network, connects the city centre of Connaught Place with the swanky Terminal-3 of the Indira Gandhi International Airport in just 18 minutes.
The Airport Express Metro currently has a ridership of over 15,000 passengers a day and is popular among thousands of fliers who used the Metro to reach the airport and nearby areas without any hassles.
