A two-year-old Guatemalan boy arrested on the US-Mexico border in early April died on Tuesday after spending weeks in hospital.
He is the fourth immigrant child since December arrested at the border. All were Guatemalans.
Guatemala Consul Tekandi Paniagua told The Washington Post that the unidentified boy is suffering from pneumonia, but his death is under investigation.
After three days in Bundeshaft, the mother of the toddler told the customs and border guards that her son was ill. He was taken to the hospital by ambulance that day.
