The Kingsport Times-News reported the details of a Tennessee Highway Patrol arrest report, which said 47-year-old Samuel Monroe Bledsoe was kicking the windows of a trooper's cruiser on his way to a hospital for a blood test.
The report says Bledsoe was then locked inside the cruiser's K-9 cage for his safety.
Trooper David Osborne said in the report that Bledsoe performed poorly during a field sobriety test - even after it was explained to Bledsoe 18 times.
The Sullivan County Sheriff's Office later fired Bledsoe.
Bledsoe was free Wednesday on $1,500 bond. A message left at a phone number listed for Bledsoe was not immediately returned.
