Some scary footage is making its way around the internet this morning. It's heart stopping stuff.
It's the moment a child fell between the platform and a train at a busy Sydney train station.
The four-year-old boy is seen on the platform with his mother, who is wheeling a pram and carrying a baby.
As they start to board the train, the boy missteps and falls straight between the train and platform.
The mother rushes along the platform, raising her arms, as shocked onlookers leap into action to retrieve him and alert the driver before the train departs.
The CCTV footage, captured in February, is being released to warn parents and carers to be extra vigilant these coming school holidays.
The little boy is okay.
