During an unannounced assessment of Border Patrol facilities in El Paso, Texas, a Department of Homeland Security watchdog found that detained migrants were kept in dirty and extremely crowded conditions, forcing some people to stand on toilets to get some breathing room.

In its report, made public Friday , the Office of Inspector General described conditions at the El Paso Del Norte Processing Center as dangerous and required immediate attention.

According to investigators, the detention center has a capacity of 125 people, yet 756 detainees were listed on its custody log on May 7. When investigators returned the following day for another unannounced inspection, the total grew to 900.

Detainees were being held in cells crowded way beyond legal capacity.

In one cell, 76 detainees were forced into a room that had a maximum capacity of 12. One 12-person cell held 76 people. Another cell with a maximum capacity of eight held 41 people during the inspectors visit, and a third cell intended for 35 people contained 155 detainees.
