According to Thai media, Lion Air staff in Thailand confirmed that a Thai woman who tried to stop 2 PRC women from jumping the queue had been beaten up and injured by the 2 offenders.
A poor resolution video of the fracas was captured by a passerby.
In the video, security guards had already separated the 3 women. However, the 2 PRC women were still aggressive and were shown chasing and throwing hits at the Thai woman.
Security had to take them to the police station and transfer them to the next available flight.
Lion Air also mentioned that the Thai woman was queuing for a flight scheduled at 10:00, while the 2 PRC women were scheduled for the 11:00 boarding.
