Tests for Mexico rig survivors

The Mexican oil rig workers plucked from the ocean are moved to a private hospital for further tests.
Most of the survivors were suffering from dehydration.
State oil monopoly Pemez said the workers went missing on Thursday after the rig was evacuated due to bad weather.
Six contractors survived the ordeal, three died and one remains missing.
The workers included four Mexicans and two Americans who were rescued in the Bay of Campeche.
One Bangladeshi worker later died in hospital.
One relative of a survivor wanted an investigation.

"Very sad after what happened and for the families that do not deserve being in this situation due to negligence by the coast guards or the company, I don't know who is responsible but authorities will investigate."
The workers for Texas-based Geokinetics abandoned their rig in the Gulf of Mexico due to Tropical Storm Nate.
