Vancouver high school stabbing was made up

Vancouver police say a girl who claimed she was stabbed on Monday at Sir Charles Tupper High School has confessed she made up the attack and the wounds were self-inflicted.

No charges are being considered in the incident and police say they are working with the school board and others to help the young girl and her family.

The entire school was locked down for several hours on Tuesday afternoon following the incident. The girl, who had slashes on her arms that required stitches, originally said she was attacked by three teenage girls in the school washroom.

"After a thorough investigation that ran through the evening and into this morning police have a greater understanding of yesterday’s events. Based on interviews and follow-up police now believe that there was no altercation and are no longer searching for any suspects," said Const. Lindsay Houghton.
