Police in Athens have arrested an elderly woman and her son for possessing dozens of antiquities they had allegedly illegally excavated on their property, authorities said Monday.

The suspects, aged 85 and 50, were found in possession of some 90 artifacts, police said.

The finds included more than 20 pottery vases, some 50 glass vials, clay figurines of a woman and animals, and two silver coins.

Police said the suspects were not believed to have planned to sell the collection on the illegal antiquities market.

Under Greek law, all antiquities found in the country are state property.
