Mrs. Benson and her 3-year-old son Michael were riding an escalator. Mrs. Benson heard a piercing scream for help and looked back to see that Michael's shoe lace had gotten caught in the escalator. His foot was being pulled into the mechanism as the escalator continued moving. Mrs. Benson grabbed Michael and tried to free his foot but was unable to. Bystanders rushed to help and were able to turn off the escalator, freeing Michael's foot which was badly injured. Michael was rushed to the hospital.
