Egypt has asked Interpol to help track down a 3,000 year old sculpture of the famed boy pharaoh Tutankhamun.

Christie’s auctioned it off last week in London despite Cairo’s objections.

The Britain-based auction house sold the brown quartzite head depicting King Tut for almost $6 million.

Christie’s has denied any wrongdoing, saying it carried out “extensive due diligence” to verify the provenance of the statue and says it had gone beyond what is required to assure legal title.
