Two teen girls and a young woman have been charged with aggravated assault after an Ottawa police officer suffered injuries while responding to a loud house party in Sandy Hill earlier this week.

Police were called to the party on the 100-block of Henderson Avenue, near Osgoode Street, just before 9 p.m. Tuesday.

When officers arrived the tenant asked police to remove several people from his home. As they were doing so, three young women “became combative and assaulted one officer, causing her serious injury,” police said in a news release issued Thursday.

“Other officers responded to assist and the three females were taken into custody.”

The officer went to hospital to be assessed as a precaution. She was then released, Ottawa police spokesman Const. Marc Soucy said.

A 16-year-old girl, 17-year-old girl and 18-year-old woman are each charged with one count of aggravated assault on a police officer.

An 18-year-old man was charged with several firearms and drug-related offences after large quantities of cocaine and psilocybin mushrooms were seized from the home, along with a few MDMA pills. A rifle, shotgun and ammunition were also found and seized, police said.
