VANCOUVER -- Accusations are being made in the suicide death of Amanda Todd through videos and messages claiming to be from the online activist group Anonymous, which says it knows the identity of the girl's stalker.

They have named a Vancouver-area man, saying on an online post "at the most this is the person who did this to Amanda Todd, and at the least it's another pedophile that enjoys taking advantage of children."

Todd, 15, committed suicide Wednesday following years of bullying and detailed in a YouTube video last month how the harassment began after an online stalker sent nude images of her to "everyone" she knew.

Mounties are currently investigating past and present social media links connected to Todd.

An online user name, with unclear ties to a New Westminster, BC, address, is referenced in multiple clippings compiled by Anonymous from several websites over the years. One website suggests the user "blackmailed" and gave advice to girls.

The same user name is tied to a forum for teen sexuality, the post reads, and another website with a "jailbait" photo gallery.

"We have brought this announcement forwards solely for the purpose of releasing Amanda Todd's punisher's identity," said a YouTube video posted Monday, claiming to be from Anonymous.

"Below, you will find a URL to the man's DOX. In there, you will see various information about said person."

The post also details how a group - which doesn't openly list any affiliation to Anonymous - has labelled the online user as "Blackmailer of the year" in a video posted in January last year.

During a memorial gathering for Todd on Monday, her friends said they've been aware of an unknown man in his 30s "stalking" their friend for years.

"There were multiple accounts with random names. There were Twitter accounts also used," one of Todd's friends who was sent the images, told QMI Agency.

"There's actually a virus right now that's posting on people's walls, saying, ‘Girl commits suicide on webcam.'

"And even if you don't like it, it gets posted onto your wall."
