PHOENIX -- A driver with a medical emergency led officers on a chase, which lasted several miles through Phoenix Tuesday night.
The Arizona Department of Public Safety was called when a driver side-swiped a fire truck inside the Interstate 10 tunnel in central Phoenix and kept going.
Officers caught up with the vehicle on Interstate 17 near Grand Avenue but could not get the driver to stop.
They deployed stop-sticks, which gradually deflate tires.
At the start of the pursuit, the driver was going 25 to 35 miles per hour, according to DPS Officer Jake Pruett, but he accelerated to speeds near 100 mph as he neared the ramp to the Loop 101.
"He was all over the place going 90 or 100, getting literally just a foot behind other vehicles," Pruett said. "We're lucky no one got hurt."
The tire spikes finally shredded the driver's tires near the Loop 101 and 51st Avenue in North Phoenix.
"He did stop, but then tried taking off again," Pruett said. "He got out and was really disoriented, but was taken into custody without incident."
Firefighters on scene tested the driver's blood sugar and found it extremely low. They took him to the hospital for treatment.
He has been identified as Michael Talley, 52.
Pruett said because this was a medical emergency, it is unclear what, if any, charges Talley might face.
