Police found 41 migrants in the back of a refrigerated lorry during a routine highway check in Xanthi, northern Greece on November 4.
According to local police, all of the migrants were male and the younger ones were taken to hospital for precautionary measures.
A Georgian truck driver has been arrested.
The footage also shows the checkpoint which the truck would have attempted to pass through.
This incident comes a few weeks after 39 Vietnamese migrants were found dead in the back of a refrigerated truck in Essex. Both trucks have been traced back to Bulgaria.
