Today's paper has a slightly different story on the front page about the incident. Apparently the tourists parked at the bird sanctuary and had planned a hike to Oyster Pond. Instead of going all the way to the end and turning left onto Oyster Pond Road, they took the first left and entered the Belvedere neighborhood which is where the robbery and assault took place. They went back to the bird sanctuary to report it and that's how the confusion apparently started.
The rest of the story concerning the arrests appears to be the same as previously reported before being taken down.
