Nine immigration police have been transferred to inactive posts following their appearance in viral video clips where they were seen escorting Chinese superstar Jackson Wang at Suvarnabhumi airport.
The incident led to extended waiting times for other passengers at the immigration counters.
Passengers at Suvarnabhumi had filed complaints, alleging that the officers had provided special treatment and police protection to Wang, causing delays in the service at immigration counters on Tuesday.
In the video footage, hundreds of fans were waiting for the Hong Kong-born superstar at the airport, with the nine officers accompanying him.
A source said foreign passengers had also complained about the extended waiting times for entry stamps during the celebrity's arrival.
