"The situation is getting worse by the day," warns Amy Fischer, an organizer with Migrant Solidarity Mutual Aid. "It is an office; it is not intended to detain people."

The conditions include one meal a day that consists of a single burrito, some 40 to 90 people at a time crammed into a single room with no beds, and some detainees held as long as seven days with no ability to bathe, according to accounts shared with MSNBC by attorneys and a family member of a person being detained.

“They just give us one burrito with water,” said the immigrant, who already had an active immigration case when he was picked up. His father spent at least six days at the Chantilly ICE office and also was given one burrito per day, and the crowding was so severe that his father had to sleep sitting up at times, the son told MSNBC.
