Several police units responded to a house party in Lindenwoods after it got out of control.
It happened at a home on Park Royal Bay just after midnight Saturday.
Police say seven young people had to be treated after bear spray was released at the party.
Police say it appears some people showed up that were not invited and the situation escalated from there.
No one has been arrested yet but police say charges could be pending and the investigation is continuing.
