(CNN)A quest by Egyptian authorities to discover a secret chamber in the tomb of Tutankhamun has ended with a frank admission -- that it doesn't exist.
'Secret chamber' in Tutankhamun's tomb does not exist, say researchers
The investigation was launched after British Egyptologist Nicholas Reeves had suggested that a secret tomb, possibly belonging to Queen Nefertiti, was concealed behind the north and west wall paintings of Tutankhamun's burial chamber.
Reeves had theorized in 2015 that the tomb belonged to Nefertiti, the wife of Tutankhamun's father, King Akhenaten.
But according to a statement from Egypt's Ministry of Antiquities, months of tests carried out by Italy's Polytechnic University in Turin, which used ground-penetrating radar (GPR), provided "conclusive evidence of the non-existence of hidden chambers adjacent to or inside Tutankhamun's tomb."
