Terrifying moments were all caught on camera as tunnel wind blows a child in a stroller onto London subway tracks.
British Transport Police released surveillance images from the incident last month.
Authorities say a man placed the stroller against a wall before going up the stairs to help other family members with luggage.
Moments later, you can see the child in the stroller rolling onto the tracks, just after a train left the platform.
Next, the images show a woman, presumably the child's mother, running to the platform and onto the tracks.
She grabs the stroller and pushes the child back to safety right before a 2nd train arrives.
Authorities want to track down the couple to make sure the child wasn't injured in the fall.
