Police say members of an Arizona State University fraternity vomited milk from a campus bridge and caused a car crash that injured two people.

Tempe police Sgt. Steve Carbajal says the prank caused a woman in one car to stop in the road Monday night. Another car smashed into it from behind.

He says the woman and her 6-year-old daughter suffered only minor injuries.

University police say they are investigating the alleged prank.
