Police chase prisoner in stolen police SUV

DALLAS - It was a wild night for Grand Prairie police after jail inmate stole a police SUV after being released from the hospital. The inmate led officers on a chase before crashing Thursday.

Luis Alarcon Jr. is back in the Grand Prairie jail after police say he was taken to Parkland Hospital for medical treatment.

When he was released, police say they wheeled him out and put him in the back seat of the Chevy Tahoe squad car. As the officer returned the wheelchair and came back, Alarcon was gone and so was the squad car.

The Parkland Hospital parking lot is where it all started just after midnight.

Investigators believe the rear door locks may have malfunctioned, allowing Alarcon to simply get out of the backseat and jump into the driver's seat and take off.

Dallas police quickly chased Alarcon for nearly 30 minutes before he crashed down a highway embankment in North Richland Hills.

Investigators are trying to determine exactly what happened with the backdoor locks but say 20 of the 2016 Chevy Tahoes have been sent to the shop to ensure they are permanently disabled on the inside.

Police have not released dash camera video or any surveillance video from Parkland Hospital.

Police are trying to determine if the officer violated any policies.

Alarcon is now facing felony charges for evading arrest and the unauthorized use of a motor vehicle.
