Arrest of Chihuahua migration chief spotlights abuses in Mexican system

Last month's fatal fire in Ciudad Juarez is latest in a series of deaths and injuries dogging the country's militarized migration agency

Mexican authorities have arrested the head of migration for the state of Chihuahua in connection with a fire which killed 40 people at a government-run detention facility in the northern border city of Ciudad Juarez last month.

The death of the migrants sparked outrage across Mexico after surveillance footage showed that officials failed to unlock the doors of the holding cell where migrants were trapped.
