A Boston Duck Tours boat rescued a child under two and his father from the Charles River near the Royal Sonesta Hotel in Cambridge around 9:30 a.m. on Monday. The child had fallen into the river after squeezing through a railing, and the father jumped in to save him. Duck Boat operators Mike Rosario and Kevin O'Neill, who were on a training run, spotted the pair and brought them aboard, delivering them safely to a nearby dock. Both were evaluated by EMS on shore, with the child being taken to a hospital as a precaution. The incident is under investigation by Massachusetts State Police and Cambridge emergency services.
