Possibly dufo but all I'm seeing is a poor article by a local radio station.
Avherald said last week that the "The UK CAA added on Feb 25th 2017, that as long as Czech Republic's CAA is investigating, the operating permit has been taken away from Van Air Europe"
The radio article mentions a loss of AOC and a suspension in consecutive sentences. There appears to be no publication of any kind from any CAA.
