Two people and a baby were found inside a stolen car, tracked through OnStar, officials said Tuesday.
The incident began after the owner of white Chevy Traverse called police at around 1:30 am.
He was able to use his OnStar tracking app and located the car on southbound Interstate 15 near Rancho Bernardo Road.
Officers caught up with the suspect just a half mile away from Mira Mesa Boulevard.
Inside, officers found a man and a woman with a two-month-old baby.
The man was identified as the driver and was taken into custody. The woman was briefly detained but then released with the baby, officials said.
