Egypt: Grocer transported antiquities with vegetables?

Presumably he was bringing his vegetables in from the countryside around Cairo:

An Egyptian grocer found himself behind bars on Tuesday for fencing antiquities. An Egyptian grocer found himself behind bars on Tuesday after police caught him with suspected antiquities concealed in food packaging, state-run newspaper Al-Ahram reported. Police searched the car of the 33-year old grocer as he was waiting for customers on a road south of Giza in the early hours of the morning, the report said. 

I've not located the original report, so cannot see the alleged antiquities (which are probably a stock photo anyway). But was he really transporting antiquities, or was his car searched and he arrested for some other reason?
