At least six girls, including some as young as 13 are facing charges after a violent robbery in Winnipeg’s northeast corner.

Police said three women, ages 16, 19 and 20, were walking near Headmaster Row and Rothesay Street when a larger group of girls attacked them.

The group of six assaulted and and robbed the group of three before fleeing, police said.

A short time later, six girls were found nearby. Now, two 13-year-old girls, two 14-year-old girls and two 15-year-old girls are all facing charges of robbery with violence.

Constable Eric Hofley said it's certainly an unusual case. 

It's "beyond the comprehension of most of us," he said. "Fortunately, this type of incident doesn't occur very often and as such it just makes it more the shocking when it does."

The 13 and 14-year-old girls remain in police custody, while the older girls have been released on a promise to appear.
