COOPER TOWNSHIP, Mich. -- Authorities say a vehicle slammed into a group of at least eight bicyclists in western Michigan, leaving an unknown number of people dead and others injured.
Kalamazoo County Undersheriff Paul Matyas tells WZZM-TV and WOOD-TV it is unclear how many people have been killed in the early Tuesday evening crash near a park in Cooper Township.
Matyas says a driver struck the bicyclists and fled on foot but has since been arrested.
He tells the television stations some of the people struck are children.
The Associated Press left a message Tuesday seeking comment from Matyas.
Cooper Township is south of Grand Rapids.
No further details were immediately available.
