PHOENIX — A van carrying 20-25 suspected undocumented immigrants caused a car crash Monday morning which left the van flipped on its side after slamming into two cars.

Witnesses say that as soon as the van rested on its side, undocumented immigrants sprang from it and ran into a nearby residential neighborhood. Authorities had been chasing the van when they first noticed it driving erratically on the highway. They were in pursuit in hopes that the driver would lead them to a drop house. However, the chase was called off when the van neared an elementary school.

Police caught 21 people and took those with injuries to a nearby hospital.
