London: British Transport Police have released harrowing images of a child in a stroller being blown by tunnel wind onto London subway tracks and a woman leaping to the rescue moments before a train arrived.

Authorities say the July 23 incident occurred when a man placed the pram at the base of a Goodge Street station staircase before going to help others with luggage. The images show the stroller rolling to the tracks and the woman jumping to the tracks in terror to grab the baby. Police are seeking to identify the couple.

The CCTV images were released Monday.

BTP chief inspector Mark Lawrie says police want to "ensure the child wasn't injured".
