Police in Chilliwack B.C., are warning parents about so-called "little girl" parties, in which older teenagers encourage middle school girls to get drunk and engage in sexual activities.

Known by the short form LG, RCMP say the parties are hosted by high school students, who invite 12 and 13-years-olds over Facebook.

"The intent of these parties and the group mentality that goes along with them is what makes them very frightening for parents and police alike," Const. Tracy Wolbeck said in a news release.

But Corinne McCabe, superintendent for the Chilliwack School District, told ctvbc.ca that while she has heard of the phenomenon, she has not been notified of any LG parties in local schools.

"I haven't personally heard or seen anything related to this in our schools," she said.

"But I think we are all worried about the dangers of online communications and how kids can get pulled into things."

McCabe said that she will provide Chilliwack principals and counselling professionals with the release.

And she believes that the public warning is a good one to get out with graduation season coming up.

"Kids just don't think before they act."

This is the second time this month that B.C. parents have been warned about schemes to victimize young girls circulating via Facebook.

Just last week, the Surrey School District warned parents that boys in Grades 11 and 12 were involved in a competition on the social networking site to see who could have sex with the most Grade 8 girls.
