Teens face charges after girl, 13, was allegedly chased and bullied in Nanton, Alta.

Six teenagers in southern Alberta are facing criminal charges after a 13-year-old girl was allegedly chased and bullied.

RCMP say in a news release that officers responded to several complaints in Nanton, south of Calgary, about the girl being chased through town on May 31.

Officers started an investigation and found a long history of inappropriate behaviour between the group and the girl.

Police say they have arrested and charged five 14-year-olds and a 15-year-old, none of whom can be named under the Youth Criminal Justice Act.

They are facing a total of 10 criminal charges that include intimidation, mischief and uttering threats.

All six have been released from custody and ordered to appear in Fort Macleod provincial court on July 15.

Cpl. Tom Nairn said it's unfortunate that multiple past warnings have been ignored.

"The RCMP takes bullying and related criminal offences seriously and will continue to protect the community and victims," he said in a news release Monday.

Police said the investigation into the matter continues.
