The Delhi Police has registered a case in connection with the recovery of a foetus from a lavatory of an AirAsia plane after it landed here from Guwahati on Wednesday, said a senior police officer.
A post-mortem was conducted on the foetus on Thursday to determine its gestational age, he said.
When an alarm was raised by the cabin crew about the discovery on Wednesday, a 19-year-old taekwondo player had admitted that she had lost the foetus.
The woman was sent for medical examination, but she refused it.
Police have registered a case under Section 318 of the IPC, which pertains to "concealment of birth by secret disposal of dead body" and is punishable with a maximum term of two years and a fine, he added. The case has not been registered against the player, he added.
The woman was supposed to travel to South Korea on Friday for a tournament and was accompanied by her coach.
The cabin crew was doing a routine check of the lavatories when they found the foetus wrapped in toilet paper.
