This teenager was passing by a canal with his friend when a young mother passed by him with her baby. The mother was walking away when she suddenly knelt down to sort her dog's lead-out and didn't realize that the pram, with the baby inside, had rolled off into a deep canal nearby. The teenager said: "The baby was crying a lot. The mum didn't say much, she started saying she was a single mum. I don't remember her saying anything else."
