A London court on Tuesday ordered the former curator of the British Museum, Peter Higgs (photo), who allegedly stole hundreds of antiquities, to deliver to the institution an inventory of all items believed to have been taken and to return any still in his possession.

The British Museum reported in August that hundreds of artefacts from its collection had been stolen or were missing, a fact which highlighted its internal organizational failures and led to the “exit” of its manager.

Higgs, Curator of the Ancient Greek Collection and Acting Head of the Ancient Greece and Rome Department, he was fired after the thefts were discovered. A police investigation has been launched against him, but no charges have been brought against him. The British Museum has filed a lawsuit against him and says he intends to dispute the claim that he is responsible for the thefts.

Higgs was not represented at today’s hearing at the High Court in London. However, the lawyers who represent him in the criminal part of the case were present, and they refused to make any comment.

The British Museum, which exhibits priceless treasures such as the Parthenon Sculptures or the Rosetta Column, says the stolen items include gold rings, earrings and other jewelry dating from the Roman and Ancient Greek periods. His attorney, Daniel Burgess, said in court documents: “While the full extent of the thefts is unknown, it is currently believed that more than 1,800 items were stolen or destroyed and several hundred of these were sold or put up for sale” by Higgs. The curator, according to the lawyer, “tried to cover his tracks by using, among other things, false names, forging documents and files stored in the Museum’s IT systems.”

So far they have been returned to the British Museum 356 items.

Judge Heather Williams issued an order ordering Higgs to return any items still in his possession and to provide information on the whereabouts of those that are missing or what happened to the proceeds from the sale of the rest.
