HAMILTON - Police say two people were hospitalized after an aerosol irritant was sprayed at a house party in Hamilton.

Hamilton police say the irritant was sprayed at the party late Friday night, where hundreds of university students were in attendance.

Investigators say there was an argument between two males, which led to one of the males spraying the irritant.

They say 10 to 15 people were affected by the spray, including two people who were taken to hospital to be treated and were later released.

Police also say the other people were treated at the scene.

Police say they have not confirmed what type of irritant was sprayed and that the male suspect fled the scene and has not been identified.
