Members of an Arizona State University fraternity vomited milk from a campus bridge and caused a car crash that injured two people, police said.
Tempe police Sgt. Steve Carbajal said the prank caused a woman in one car to stop in the road Monday night. Another car smashed into it from behind.
He said the woman and her 6-year-old daughter suffered only minor injuries.
University police are investigating the alleged prank.
