SINGAPORE - The incident at Orchard MRT station on Monday evening that led to four people getting injured was due to the escalator they were on suddenly halting, causing them to fall, the Land Transport Authority (LTA) said yesterday.
The escalator in the station underpass connects to Scotts Road, outside Tangs department store.
Two girls aged 13 and 11 suffered lacerations and abrasions on their legs.
They were taken by Singapore Civil Defence Force (SCDF) paramedics to the KK Women's and Children's Hospital.
One woman in her 60s suffered back pain from the incident, and another woman in her 40s had lacerations on both legs and on her right eye brow.
Both were taken to Tan Tock Seng Hospital.
The incident happened at about 7.30pm.
A spokesman for the LTA said that it "takes the issue seriously and will be investigating the cause of the incident".
The escalator will remain closed while the LTA investigates, she added.
In 2010, an escalator at Ang Mo Kio Hub caught fire when machinery under the floor plates burst into flames.
No one was injured.
