Four people were sent to hospital after one of the commuters felt unwell on an escalator and fell into the other three at Hong Kong’s Lam Tin MTR station on Saturday.
Police said officers were alerted to the incident at 1.40pm and noted it took place near the station’s D exit.
All four people were sent to United Christian Hospital in Kwun Tong, the force said.
A source said a 33-year-old man and his 62-year-old mother were on the ascending escalator when the former suddenly developed a cramp in his right leg and fell backwards.
His mother tried to support him but lost her balance, resulting in the pair knocking down two other women, aged 58 and 73, the insider added.
The source said all four suffered minor injuries, with abrasions on their hands and feet.
