"Interrogator": "Why did the people the couple get off the train and started running on the track", 
"Interrogee": "So when the train stopped, the couple started running because they were actually the gang leaders, and they were done with their examination or monitoring of the gang members. Now they were trying to escape from the CID team, so they tried to flee. However, the CID chased them and captured them. Then they asked the old couple what's happening and why they were running. The old couple tells them everything, and then the CID members say that they should get to the next station. They should ask their fellow team members to capture all the gangsters before they reach the next station."
