A TEENAGE girl who committed suicide after being bullied online sent most of the hateful comments to herself, bosses at the social network site Ask.fm have claimed.

Hannah Smith, 14, from Leicestershire, England, killed herself two weeks ago after apparently suffering months of abuse at the hands of online bullies who told her to kill herself, cut herself and “drink bleach”.

Her case led to UK Prime Minister David Cameron urging parents and teenagers to boycott what he described as "vile" websites.

However, Latvia-based Ask.fm, where the bullying supposedly took place, say that after analysing the user profiles of the messages sent to Hannah they found most of them came from the British schoolgirl’s own computer.

According to the Sunday Times, sources at Ask.fm claim 98 per cent of messages had been sent from a computer with the same IP address as Hannah's with only four posts coming from elsewhere.

A source told the paper: "With the Hannah case they looked at every identity - the IP addresses are trackable. She posted the anonymous messages herself.”

Seeking to explain the unusual finding her father David Smith said she may have posted the abuse as a desperate attempt to protect herself.

In a post on his Facebook page Mr Smith wrote: “Mybe she was but she was tryin to do anything to stop people from bullyin her hannah was bullied at school on her phone and on the internet she was a desperate little girl that had been ground down...”

Meanwhile, an internet troll has allegedly owned up to some of the bullying.

According to the Sunday Mirror, the 16-year-old, from Tongeren, Belgium, revealed himself on another social network, saying he was fearful of going to jail.

The boy reportedly wrote on mobile messaging app Kik: “you no that girl that's all over the news and s**t... hannah!? The day before she died i was sending her a load of abuse get cancer kill yourself e.t.c i didn't think it would go this far."
