The standoff lasted for five hours before the bus retreated back into the Phoenix detention center.
Immigration activists from the Arizona Dream Act Coalition were holding a vigil outside a Phoenix immigrant detention center when a bus filled with immigrants tried to leave the facility.
The "dreamers," undocumented youth brought to the country as children, and their mothers, ran towards the bus.
"It was weird, all of the families and moms everybody started running to get in front of the bus," high-profile "dreamer,' Erika Andiola, who was at the vigil, told BuzzFeed.
