The police have found about 30 migrants and one dead person in the trailer of the truck, says the Czech police.
A foreign truck was stopped on Monday afternoon on the highway about 18 kilometers from the capital Prague. According to the police, people who escaped from the truck were searched by helicopter and traffic on the highway was stopped.
The nursing staff had treated a 30-year-old woman found unconscious on the spot, who was declared dead after resuscitation.
The police did not provide more detailed information about the migrants. However, the vehicle is believed to have been on its way to another country from the Czech Republic, which is a transit country for many migrants to Western Europe.
