A plane carrying 350 migrants from Texas landed in Rockford early Sunday, and the asylum seekers were then sent to Chicago.

According to the city of Rockford, after the plane landed around 1 a.m., those onboard were immediately put onto buses to Chicago’s “landing zone” in the West Loop.

Winnebago County Sheriff Gary Caruana, who helped coordinate efforts on the ground at the Rockford airport, said local officials were notified Saturday afternoon that the flight of migrants was coming.

“They did give us time to prepare, and we did prepare a plan,” he said. “What the problem was, was they said they were going to get here around 9 or 9:30 [p.m.], and actually it was later. It was like 1:30 in the morning.”
