A group of Chinese national passengers claimed that they were 'assaulted' by Changi Airport staff and police when they were protesting over a 9-hour delay of a Hong Kong Airline flight from Singapore to Hong Kong.

An airline spokesperson said that CCTV footage of the incident showed that the Singaporean ground staff had acted appropriately.

According to news reports shared by a STOMPer, the Airbus 330 carrying 159 passengers had been delayed in Singapore for almost nine hours due to a technical fault.

Some of the passengers claimed that they were "assaulted" by airport staff and security after they tried to block a walkway in Changi Airport.

They said a policewoman had knocked into an old woman with a luggage cart and hurt the old woman's hand.

One of them even claimed that the airport police were "taking out their weapons and handcuffs" to threaten them.

Their protest continued in Hong Kong when the passengers refused to leave the plane when it landed at 5.30am yesterday (Nov 16).

The matter was finally resolved eight hours later when Hong Kong Airlines agreed to compensate each of them with HK$1,200 (about S$200).
