Not less than 41 people have been rescued alive in the back of a refrigerated truck by the police during a routine highway check in northern Greece.

Police spokesman, Theodoros Hronopoulos told CNN that the refrigeration system had not been turned on and migrants were uninjured.

Recall that 39 migrants were found frozen to death in a truck container last week on their way to Europe. The migrants who were from Vietnam had attempted to cross over to Europe in search for greener pastures when they met their Waterloo.
