Terrance King was arrested Wednesday behind the wheel of a stolen ambulance.
Hospital security departments had been watching for him. He was spotted several times last week wearing a lab coat taken from another hospital.
Police say around 9:40 Tuesday night, King was at different facility, Medical City Hospital in North Dallas, when police say he stole the ambulance.
Court records indicate that the ambulance was privately-owned.
The arrest warrant affidavit details the responding officer requested permission to chase and was denied.
The document also says, "The [suspect] had turned on the emergency lights of the stolen ambulance so the officer was able to visually track the vehicle from a distance."
Police say while on his joyride Tuesday night, he led officers to the E.R. at Parkland Hospital. That's where an alert Dallas County hospital district police officer spotted the vehicle leaving in the wrong direction.
Then, at an intersection at Maple Avenue and Oak Lawn, police say King crashed into a white BMW and then took off running.
A witness at a nearby gas station told police the suspect approached him at this gas station. The officer wrote that the suspect "...Had run up to witness, who was at the nearby gas station and asked, ‘Can I get a ride to a bus station, I stole that ambulance.'"
It goes on to say that the "Witness told the [suspect] ‘no,' and the witness then observed the [suspect] take off running."
Officers say this is not the first time King has done something like this.
He was also arrested in 2013 after he showed up at a Plano firehouse pretending to be a Dallas firefighter.
He has a criminal history that includes theft and burglary.
