Mexican authorities have detained six men suspected of stealing a truck carrying medical equipment, including a radioactive element.
The suspects had been admitted to a hospital in Hidalgo state with possible symptoms of radiation poisoning but have since been released.
The truck was stolen on Monday and found abandoned two days later in a nearby field.
