Swiss police have arrested a man in connection with the discovery of a 2,000-year-old Roman fresco in the city of Zurich.
The work - depicting a peacock - disappeared from the Italian town of Pompeii in 1957.
Dating from 79 AD, it had been in the possession of a Zurich collector until earlier this year. According to Italian police, the collector had unwittingly bought the piece from a Swiss antiques dealer, but had handed it over to the Italian authorities in February.
The suspect has not been identified.
The arrest came as part of efforts on behalf of the Italian authorities to trace missing works of art, including five paintings by Italian Grand Masters from the 14th to 18th centuries.
