ONTARIO, Calif (KABC) -- A police dog helped subdue a suspect after a lengthy standoff on the 15 Freeway in Ontario that left traffic backed up for miles. The stolen-car suspect had stopped on the northbound 15 and refused to exit his vehicle after a chase from the Azusa area. After negotiating for some time, officers sent in a K-9, who leaped through the vehicle's window and latched onto the suspect's arm. The suspect continued to resist and fight off the dog but eventually multiple officers approached the vehicle and were able to take him into custody.
