The chase started around 8 p.m. with a report of a shooting at a home in Azusa.
Authorities gave chase, following multiple suspects in one car at high speeds on the 210 and 605 freeways. They went through Baldwin Park, Irwindale and near Pasadena, then eventually ended up in the Azusa/ San Dimas area.
The car then smashed into another car that was turning left in front of a Trader Joe's in San Dimas. Multiple suspects jumped out and ran away on foot. At least five were taken into custody within a few minutes.
Three people, including a child, were in the car that was struck. They were evaluated by paramedics and did not appear to have serious injuries.
