EL PASO, Texas (CBSDFW.COM/AP) — An inspection at an El Paso Border Patrol station where detained migrants are held found in May, there were 900 people crammed into the 125-person facility at one point.

The Office of Inspector General for the Department of Homeland Security found “dangerous overcrowding.”

Most of the detainees were held past the maximum allowed 72-hour period.

Inspectors found migrants held in standing-room only spaces for days and some standing on toilets.

An unprecedented number of families with children have arrived at the border this year.
