Investigators found nothing suspicious in the bag. In the meantime, a couple claiming to be BJP workers reached the spot and said the bag belonged to them.
"The couple had kept the bag at the BJP headquarters and had gone to the nearby Andhra Bhavan to have some food. Meanwhile, somebody made a police control room call about the unclaimed bag," Additional Commissioner of Police (New Delhi) SBS Tyagi said.
"The husband and wife were brought to the police station for questioning," he said. The police said prima facie there seems to be nothing serious but they are investigating the matter.
