Police found nine migrants hiding in a refrigerated truck, after one called police due to being so cold.
The migrants were found on Thursday night (February 9) by police in a parked truck, the Belfast Telegraph reported.
The migrants - six of whom were from Vietnam and three from Iraq - had travelled from Belgium across the border into the Netherlands, where they were found.
All nine migrants have now been taken into care by the police. Police said none of them needed medical treatment after the incident.
The driver of the truck, who is Spanish, has been detained.
