A cyber-stalker who carried out a "vicious, vitriolic and vindictive" harassment campaign against a July 7 bombing survivor was jailed today.

Campaigner Rachel North, 36, feared for her safety after Oxford-based researcher Felicity Jane Lowde, 41, used her blog and email to wage a hate-filled crusade of harassment for more than a year.

Among more than 100 postings Ms North, who gave up her job to fight for an independent inquiry into the bombings, was accused of "making a living on the backs of the dead" after she wrote about the Russell Square Piccadilly Line bombing which killed 26 people.

Lowde, of Jackson Road, in Cutteslowe, was convicted of harassment in her absence when she failed to appear in court in April this year and went on the run.

Today she was jailed for six months and given a restraining order plus an Asbo lasting five years at London's Thames Magistrates Court.

Lowde told the court she intends to appeal her conviction.

Judge Malcolm Read told her that she had struck at Ms North's "terrible experience and trauma" as a victim of the London bombings.

She then "aggravated" the situation by breaching her bail conditions and continuing to persecute Ms North even though police were involved.
