Chicago: Passengers of a US flight heading to Dallas, were left horror-struck mid-way through their journey, after the staff discovered a human heart lying onboard.

It was later found out that the heart was a part of “life critical cargo shipment” and was meant for a delivery back in a Seattle hospital, news agency AFP reported.

Meanwhile, the airline has not given any other details as to which company shipped the human organ or any other information regarding the incident.

In a separate and earlier incident, the Delhi Police registered a case in connection with the recovery of a foetus from a lavatory of an AirAsia plane after it landed here from Guwahati yesterday, a senior police officer said. A postmortem was conducted on the foetus to determine its gestational age, he said.

When an alarm was raised by the cabin crew about the discovery, a 19-year-old taekwondo player had admitted that she had lost the foetus. The woman was sent for medical examination, but she refused to undergo tests. The woman claimed she was not aware of her pregnancy and even her brother-in-law said her family was not aware she was pregnant.
