PHOENIX -- Several people were caught running through a Valley neighborhood after bailing out of rolled van near 27th and Southern avenues.

Chase ends in rollover

The Department of Public Safety had been following the van as it drove erratically through Phoenix. The pursuit started in the area of Interstate 10 and 44th Street. DPS initially started following the van in the hope that it would lead them to a drop house.

After getting off the freeway, the driver of the van refused to stop, plowing though barricades and over medians. DPS said the van even tried to ram one of its cruisers.

DPS said it suspended the chase when the van entered a school zone.

The van was eventually involved in a wreck. It ran a stop sign, and then slammed into another car and rolled over. As soon as the van rolled, about two dozen people, suspected illegal immigrants, bailed out and ran through the neighborhood.

Video from NewsChopper 3 showed several people hopping over fences going from backyard to backyard.

Officers with guns drawn were on the scene to corral the people. The Phoenix police Department said 21 of the runners have been taken into custody. Police are still searching the neighborhood. They believe there were as many as 20 to 25 people in the van when it crashed.

Police said several people have been take to the hospital for treatment, but no major injuries were reported.

DPS said investigators believe they have the driver of the van in custody.
