A cyclist is in serious condition after being struck by a car on Saturday morning in Stillwater, Minnesota. 

The Washington County Sheriff's Office said officials responded to the 12000 block of Dellwood Road North just before 9 a.m. for a report that a man on a bike had been struck by a car. The man was treated at the scene and then taken to a local hospital. 

Officials did not say if the driver remained on scene or if anyone was in custody. 

The Washington County Sheriff's Office and the Minnesota State Patrol are investigating the incident. 

At least three other pedestrians were struck in Minnesota over the weekend: a 32-year-old man in St. Paul, a 64-year-old woman in Fairmont and a man of an unknown age in Minneapolis. They all died from their injuries.
