Stomp contributor Alan was shocked to see a boy whose hand got trapped between lift doors at Suntec City at 2.30pm on Dec 13.
Alan was on his way to Popular Bookfest when he heard the boy screaming for his mother.
That was when he noticed that the boy's hand was trapped between the doors.
Alan said many passers-by and security staff rushed over to help the boy.
Working together, they managed to free the boy's hand within three minutes, according to Alan.
"It was a really scary incident as without the help of these men, this boy's hand would have been fractured or broken," said Alan.
"In future, when I bring my primary school students out for trails and events, I will relate this experience to them."
"Maybe I can even show them these pictures on my blog", he added.
