The tourists told police that they had stayed in Calais overnight after arriving on the Eurotunnel and it is believed that is where the stowaways got into their car.
The two migrants fled but were then caught by local police. As they were minors prosecutors in Dieppe issued a care order, but French media report that social services refused to take them into care so they have now been released.
In order to make room in the luggage box, the men had thrown out items of luggage, so the two tourists filed a complaint for theft.
