The researchers posed as honest finders and handed in the wallets to ten different police stations across Flanders. The wallets contained information about the owner's identity as well as 150 euros in cash.

In seven of the ten cases the wallets with the contents were returned to the rightful owner. More disturbingly in two cases the wallets went completely missing and the owners received no notification whatsoever.

The owner of the last remaining wallet was notified, but when he turned up to collect it his possession had disappeared.

The police officer who contacted the owner conceded that the wallet had probably been stolen at the police station in Ghent. A police report was drawn up about the incident and the internal surveillance department was notified. The police station returned 150 euros, but the whereabouts of the wallet remains a mystery.
