Facebook tribute pages to a bullied schoolgirl who apparently committed suicide have been targeted with hate messages.
Amanda Todd, 15, was found dead last week after posting a video on YouTube describing her torment.
Two Facebook pages set up in tribute to the Canadian have nearly one million combined 'likes', but among the messages of mourning are abusive posts and images.
One picture showed the silhouette of a female body hanging dead along with the mocking phrase: "Todding."
Other people who commented said she deserved the negative attention that she had received from bullies.
Sergeant Peter Thiessen said police are aware of the new posts.
"It’s really a matter of those who are involved in it to realise the impact of what they are doing and that they are bordering on criminal acts. If we get that type of evidence then we would be quick to lay a charge."
In a nine-minute video posted on September 7 on YouTube, the British Columbia cheerleader did not speak but told her story in a series of handwritten notes that she held up to the camera.
She said she was lured by a stranger to expose her breasts on a webcam and the picture ended up on a Facebook page made by the stranger, to which her friends were added.
She wrote of being pushed into anxiety, depression, drugs and alcohol.
Amanda said she changed schools but an encounter with another girl's boyfriend started the bullying again, which this time escalated into a physical attack in which she said she was beaten.
When Amanda got home, she wrote, she drank bleach: "It killed me inside and I thought I actually was going to die." She was rushed to a hospital to flush out the bleach.
More anxiety, cutting and overdosing followed, and despite counselling and antidepressants, she was rushed to hospital again after an overdose.
The last cards in the video said simply: "I have nobody. I need someone. My name is Amanda Todd."
Beneath the video, Miss Todd posted a note saying: “Everyone's future will be bright one day, you just gotta pull through. I'm still here, aren't I?"
Amanda died in her home on Wednesday. Coroner Barb McLintock said on Thursday that preliminary indications suggest Amanda killed herself.
