4 women between 50 and 60 years old fell down while riding on an escalator at Bishan MRT station on the morning of 8 January.
The women reported that the escalator had allegedly changed direction abruptly without warning, forcing them to lose their balance and sit on the escalator steps.
Station staff attended to the women, who did not sustain serious injuries.
However, SMRT’s investigations have found “no malfunction in escalator operations”.
In its statement, SMRT reminded commuters to hold on to the handrails while riding on escalators in the stations.
On 12 November last year, an elderly 64-year-old man fell backwards while riding an escalator at Bishan MRT and suffered serious head injuries. He has been in a coma since then.
