According to German newspaper sueddeutsche 300 ants (or colonies) were stolen from German ant shop myants.de. A 19 year old employee tried to sell the ants via ebay. The whole thing leaked out after a request by shop owner's friend. After that the police made a house search and found the stolen colonies. The colonies are worth €3500.
According to German law buyers of stolen goods never become owners of these goods so they have to give the ant colonies back to the shop.
