BISMARCK — An alleged drunken driver was arrested after running into a Bismarck police vehicle, sending an officer to the hospital with injuries, the North Dakota Highway Patrol said in a news release.

The crash happened at 9:18 p.m. Monday, Nov. 30, on the Bismarck Expressway between the Expressway Bridge and Washington Street.

Bismarck police Officer Tyler Mahowald was helping to direct traffic as a tow truck was recovering a disabled vehicle involved in an earlier crash. That's when a westbound pickup truck driven by Roger Borud ran into the back of the parked police SUV with its emergency lights flashing, the patrol said.

After striking the police SUV, Borud’s pickup continued west and hit the tow truck, the patrol said.

Officer Mahowald was in his parked SUV at the time of the crash. He was taken to Sanford Medical Center to be treated for his injuries and was later released.

Borud, 36, of Bismarck, and the occupants of the tow truck were not hurt, the patrol said.

Borud was booked into the Burleigh Morton Detention Center on suspicion of DUI, reckless driving and having an open container of alcohol in a motor vehicle. He later posted $1,000 bail and was released, jail staff said.

As of Tuesday, court records did not show formal charges against Borud and did not list an attorney for him.
