A Polish doctor said she has been in "deep shock" since learning that a 91-year-old woman she pronounced dead woke up in a morgue.

The doctor said that she was sure the patient was dead after finding "no basic life functions" during a house call on November 6.

Prosecutors are investigating whether the patient's life and health were endangered by the inaccurate death diagnosis.

Identified by the media as Janina Kolkiewicz, the elderly woman was examined in the eastern town of Ostrow Lubelski after relatives noticed she was not breathing. She was pronounced dead and sent to the morgue.

Hours later an undertaker noticed she was moving.

An official said Ms Kolkiewicz is now in good health.
