Update to this story.

PHOENIX (KSAZ) – One day after Arizona Governor Jan Brewer fired off a letter to President Obama, concerned about dozens of undocumented immigrants being dropped off at a Phoenix bus station, another bus load of immigrants arrived.

Early Tuesday morning FOX 10 saw a bus load of people dropped off by a bus with Department of Homeland Security markings.

The Greyhound spokesperson said that Arizona is the only state they’re aware of that is getting bus loads of people.

The Greyhound bus station near 24th St & Buckeye has turned into a refuge for bus loads of immigrants being dropped off by DHS.

FOX 10 was told immigration officials are moving hundreds of undocumented workers caught in Texas who are from Central America to Arizona. DHS says they don’t have the manpower to process them all.

Volunteers dropped off Powerade, diapers, and toys for the kids.

“I’m a mother with small children, I can’t imagine how exhausted, tired, and scared the women are. So I just wanted to be able to help them in any way possible,” said Ella Herrington.

A spokesperson for Greyhound said that up until a couple of days ago they were not given any notice that large groups of people were being dropped off. They say this had never happened before.
