From the folks at Noonsite:
Cruisers Recommended to avoid the areas of Puerto Escondido and Laguna El Diamante
More information can be found at Riodulcechisme.
Seems that there are more attacks than are being reported. Take care when cruising, stress awareness to all your crew and guests.
Sorry to bring in the holiday season in this manner.
Criminals don't take the holidays off, neither should your awareness.
