A family excursion at the San Diego zoo took a scary turn when a father carried his 2-year-old daughter into the elephant enclosure. After one of the elephants charged at the man, he fell down and dropped the toddler as he scrambled to get her to safety, video of the incident shows. Authorities say the little girl was unhurt and returned to the custody of her mom. The dad was arrested on suspicion of child endangerment, the Associated Press reported.
