Dutch police say a man suspected of being a migrant has died after falling or jumping from a moving truck near the port city of Rotterdam.

Police arrested the driver of the truck on suspicion of people smuggling and also detained seven other people who were on board the vehicle when the incident happened Saturday.

In a statement, police say that they were alerted by witnesses who reported seeing people hanging out of a truck with Polish license plates. When officers drove up to the truck, a man fell or jumped out and later died of his injuries.

Police say the suspected migrants possibly come from Eritrea. Investigations are continuing into where they came from and where they were going.
