After the third robbery, West Valley City and Unified Police officers were on the lookout for the suspects' vehicle.
Two WVCPD officers spotted the vehicle at 5400 South and 4000 West and, checking its plates, learned it had been stolen. The five teens inside the car also matched descriptions of the armed robbery suspects.
Police followed the car as it drove a circuitous route through the area until another WVCPD officer successfully spiked its tires.
"Then officers pursued the vehicle for several blocks before the driver stopped ... at 4320 West and 5400 South and five occupants fled on foot," Vainuku said.
Two of the suspects were apprehended after a short foot chase, and a short time later two more of the teens were cornered by police dogs and taken into custody. The fifth youth eluded the dragnet and remained at large Monday afternoon.
Two of the victims positively identified the four suspects in custody as their assailants, but none of the teens were cooperating with investigators.
All four suspects — males ages 13, 14 and 16, and a 17-year-old female — were booked into the youth detention on suspicion of felony aggravated robbery, possession of a stolen vehicle, evading and fleeing police, resisting arrest and weapons offenses.
Those in custody — two from Kearns, two from West Valley City — all were listed as runaways with active "pick up" orders, Vainuku said.
