A 5-year-old girl who fell overboard off a Disney cruise ship reportedly fell backward through a porthole. The investigation is continuing into the incident that happened June 29 as the ship was returning to Fort Lauderdale after a four-day cruise.

The Disney Dream rescue team pulled the girl and her father into a small boat on Sunday as the cruise ship was returning to Fort Lauderdale, Florida, from the Bahamas on the last day of the voyage, according to Disney and passengers who recorded the rescue on video.

The 5-year-old fell overboard when she lost her balance while sitting on a railing and dropped backwards down a porthole, BSO said.
