The Delhi Metro Rail Corporation's Blue Line service on Tuesday was severely affected leaving the passengers either stranded on the platform or inside the trains.
"Delay in services between Yamuna Bank and Noida Electronic City due to a passenger on track at New Ashok Nagar," DMRC's official Twitter account said at 2:13 pm.
A couple of hours later, @OfficialDMRC tweeted, "Delay in service from Janakpuri West to Dwarka Sector 21."
Within half an hour, a final update was issued on Twitter, "Normal service has resumed. Please allow some extra time for the bunching of trains to clear."
Earlier on Tuesday, in a suspected suicide bid, a man in his early 20s died after an approaching train smashed his head while he lay on the platform at New Ashok Nagar metro station, police told PTI.
The man, identified as Amit Soni, a resident of Gwalior in Madhya Pradesh, laid down on the platform, with his head and shoulders sticking out towards the track, when he saw the train approaching, they said.
The train hit his head and he sustained serious injuries. He was rushed to a nearby hospital where he was declared brought dead, the police said, adding that no suicide note was recovered.
Soni's family is being informed and inquest proceedings are on, they said.
