A 30 year-old-man from Norfolk has been arrested on suspicion of attempted murder - after a three-year-old boy was left with critical injuries after ending up in a crocodile enclosure. Cambridgeshire Police were called to Johnsons Zoo near Huntingdon this afternoon. They do not believe the man and child were known to each other. The crocodile enclosure has been closed until further notice. #Norfolk #Crocodile #Zoo #News #Channel4News
