A 23-year-old tram driver was arrested on suspicion of dangerous driving after a tram tipped over in Central on Hong Kong Island late Wednesday.
Closed-circuit TV footage obtained by Oriental Daily captured the dramatic crash.
The westbound tram fell on its left side on Des Voeux Road Central near Bank Street, outside the HSBC headquarters at about midnight.
Firemen were called to the scene at about 12.02am after receiving reports of multiple casualties, HK01.com reported.
Some passengers were able to climb out of the tram windows themselves, while others had to be rescued.
Eight men and five women, aged 24 to 64, suffered minor injuries and 11 of them were sent to Ruttonjee and Queen Mary hospitals for treatment.
The driver also suffered injuries to his arms and legs. Three passengers did not require hospital treatment.
Police said the driver passed a breathalyser test and was not under the influence of alcohol at the time. He was released on bail pending an investigation and must report back to police early next month.
The location is not known as a traffic accident black spot.
By 3am on Thursday morning, the recovery team had removed the tram from the tracks and traffic resumed by 5am.
“Police will conduct an investigation … including looking into the speed of the vehicle at the time, the tram’s performance and other external factors,” Chiu Shung-hei, an officer from the Hong Kong Island traffic accident investigation team, said.
“This covers road design or whether there were objects in the tracks that could have interfered with the tram’s advance.”
He said witnesses did not report any collision with other vehicles.
Hong Kong’s double-decker trams carry around 200,000 passengers a day and have serviced Hong Kong Island for more than a century.
