Four people including one Czech and three foreigners were killed on Wednesday when the helicopter they were in crashed over a factory in western Czech Republic, local police said.
The Czech CTK news agency said it was thought that the foreign victims could be Thai nationals.
The four-seater Robinson R44-Raven helicopter came down in an industrial zone in a suburb of the town of Plzen.
“Among the victims, there are three foreigners, two men and a women,” local police spokeswoman Dana Ladmanova said.
No-one from the Thai embassy in Prague was immediately contactable.
