ASU police are investigating an incident where eight to ten fraternity members allegedly caused a car collision, University spokeswoman Julie Newberg said in a statement.
The students are suspected of drinking milk on a Tempe campus bridge and vomiting it onto moving traffic on University Drive on Monday evening.
A vehicle stopped suddenly after the driver saw something falling off the bridge and was rear-ended by another car, Tempe police spokesman Sgt. Steve Carbajal said.
The rear car was driven by a woman with her young daughter inside, he said.
ASU is investigating the allegations, but University police did not return multiple calls seeking comment Wednesday afternoon.
