A Twin Cities motorcyclist is suspected of being drunk and was arrested at his home.
This comes after police say he collided with an SUV, and then left his injured sister behind at the scene.
It happened just before 7:00 p.m. Sunday on Highway 61 in St. Paul Park.
The 60-year old female passenger, Kimberly Ann Robinson of Newport, is in critical condition at Regions Hospital. The State Patrol says she was not wearing a helmet.
The 70-year old driver was arrested at his home about seven miles away in Inver Grove Heights.
The couple in the SUV were not injured.
