A drunk driver crashed into a marked patrol unit that had pulled over another drunk driver, leading to the arrests of both drivers, deputies said.

Todd Casey, 49, and Michael Probst, 36, both of Tampa, are facing charges in connection with the incident, which happened at 10:31 p.m on Dale Mabry Highway North in Tampa.

According to the Hillsborough County Sheriff's Office, deputies pulled over a 2012 BMW for a traffic violation at the intersection with North Village Drive.

When they spoke to the driver of the BMW, identified as Probst, they detected signs of impairment. Deputies said Probst had blood alcohol content of .114 and .134. Florida presumes legal intoxication at .08.

While they were conducting the traffic stop, a 2005 Dodge sedan side-swiped a marked patrol vehicle, deputies said.

The driver continued on Dale Mabry without stopping, and finally deputies pulled him over at Fletcher Avenue W.

Deputies said the driver, identified as Casey, appeared to be intoxicated. He had alcohol on his breath, his eyes were red and glassy and his speech was slurred, deputies said.

Casey's blood alcohol content was recorded at .181 and .196, more than twice the legal limit, deputies say. He was taken into custody.

Both men are facing charges of driving under the influence. Casey is facing an additional charge of driving under the influence with property damage and traffic citation for violation of the "move over" law.
