The Saskatoon Police Service says officers responded to a report of two females fighting in the 28-hundred block of 7th Street East around 3:10 a.m. on Monday morning.

Officers located a 17-year-old female inside a home in the care of paramedics but say she left the scene shortly after. A short time later, officers located an 18-year-old female outside the residence suffering from what were believed to be serious injuries; she was transported to hospital by paramedics.

It is believed these two females were involved in the reported fight, that they are known to one another and that a baseball bat may have been used in the assault.

The Serious Assault Unit is continuing to investigate and anyone with information is asked to contact police at 306-975-8300 or submit a tip anonymously to Crime Stoppers at 1-800-222-8477.
