Police in Dayton are blaming road rage for a two-vehicle crash that injured four people including two pregnant women.
A regional dispatch center received calls three to five minutes before the Sunday afternoon crash about one vehicle chasing another.
The Dayton Daily News reports the driver of a truck not involved in the road rage chase had to be extricated from his truck by Dayton firefighters after the crash.
Dayton police Lt. Mark Ponichtera tells the paper one person involved in the crash is in "life-threatening condition" with three more hospitalized, including two pregnant women.
Police are searching for a second vehicle involved in the chase.
