It has been reported that 7 of the DREAM 30 have been released from custody.

From Colorlines:

"Elsy Núñez, originally from Honduras, and her four-year-old daughter Valeria, who is a U.S. citizen, were released late Monday—just hours after the action in Laredo, Texas. Since then, Javier Galvan, 16, and his father Javier Calderon were released; Jessica Gallegos, 16, and her sister Ingrid Gallegos, 13, were released with their mother Victoria Reyes; and Brandow Gonzalez, 15, and his mother, were released. That leaves only one minor—Luis Lopez Rivera, 17—in Customs and Border Patrol (CBP) custody. NIYA organizer Mohammad Abdollahi says that officials have indicated Lopez Rivera will be transferred to the Office of Refugee Resettlement; CBP declined to comment on the case."

I'll keep you posted as new information becomes available.
