CALGARY - Two girls fled a pack of bullies who ambushed them early Wednesday on a northeast street forcing the girls to run to a nearby school for safety.

Police said the girls, 13 and 14, who were apparently on their way to school, were jumped by a group of five to six teens as they walked near Castleridge Dr. just before 10 a.m.

Sgt. Mike Lomore said police haven't determined a motive behind the attack believed to be launched by the group of girls and boys.

There is no relationship between the victims and the assailants.

"It looks like it was a non-sensical confrontation," he said.

"Anger, stupidity."

Police, including the K9 unit, were looking for a group of dark-skinned males and females responsible for the attack.

Lomore said the frightened girls ran to a nearby school, John Paul II, for safety.

"They weren't robbed, they didn't take anything and they didn't want anything," he said.

"They were thrown down to the ground and when they let them go they ran to the school, which is a good thing."

The girls suffered superficial wounds in the attack, Insp. Darren Cave said.

Police said no weapons were seen.

A mother leaving the school with one of the attacked teens said her daughter was shaken but otherwise alright and other than that did not want to comment further.

A principal of the nearby Terry Fox school drove to John Paul II to pick up the other student.

Cave said the assailants did not appear to have any motive beyond simply outnumbering and attacking the girls.

"It's another example of bullying in it's worst form," he said.

Janet Corsten, spokeswoman for the Calgary Separate School District, which oversees the elementary school where the girls ran for help said she is happy they saw it as an option in the aftermath of the terrifying incident.

"They fled to the school as a safe haven," she said.

"When anything like that happens, obviously we want (youth) to see any school as a safe haven where they'll get the help they need."
