Detainees at Otay Mesa Detention Center threw notes in bottles over facility fences to communicate allegations of poor conditions, including inadequate food, constant sickness, and indefinite detention without court hearings. Organizers collected the bottles containing written messages along with items like lotion bottles, deodorant bottles, and batteries. Rep. Juan Vargas attempted to inspect the facility to investigate the allegations but was denied entry by officials who cited ICE authority. Detainees' written messages referenced conditions including alleged use of small cages for discipline and inadequate medical care at the detention center.
