Officers responded late Friday night to a call about a man pulling a female passenger out of a vehicle stopped next to the median on State Route 51 in north Phoenix.
Police say the 43-year-old Bundgaard and his girlfriend, 34-year-old Aubry Ballard, both had marks on their body from a physical confrontation, which constituted an act of domestic violence.
Bundgaard told police that he’s immune from arrest under Arizona law, since he’s a state senator and the Legislature is in session.
Police say Bundgaard wasn’t arrested but Ballard was booked early Saturday into a Maricopa County Jail on one count of assault.
Bundgaard has been a state lawmaker since 1995.
