Steven Brooks, a Democrat representing Nevada's Assembly District 17, was arrested Saturday and charged with threatening a fellow state representative.
Brooks, 40, was no longer in custody Monday morning, according to jail records.
North Las Vegas police arrested Brooks during a traffic stop at about 5:30 p.m. Saturday in the area of Carey Avenue and Mt. Hood Street.
He was booked on one count of intimidating a public officer by threat of physical violence.
North Las Vegas police said Brooks was held on $100,000 bail.
Brooks' arrest came less than three weeks before the 2013 legislative session.
The Assembly Democratic Caucus issued a statement on Sunday saying, "We understand an investigation is currently ongoing and we have no further comment at this time.
Brooks is a management analyst with the City of Las Vegas' Parks, Recreation and Neighborhood Department.
In a statement, a city spokesperson said Brooks' case was being treated as a personal matter and would be "thoroughly reviewed."
"Following that review, the city will take appropriate action," the statement read.
