An anti-capitalist protester uncovered as a sex offender with a string of international convictions including for rape and manslaughter has been jailed for 24 weeks.
Stuart Durkin, 50, was found by police at a protest camp in Finsbury Square, Islington, north London, last year, using the false name "Troy" to target women.
He was sentenced at the Old Bailey today for failing to comply with notification requirements enforced on him as a sex offender, and breach of bail conditions.
Durkin has a string of previous convictions for violent and sexual crimes.
He was jailed for six years in Sweden in 1984 for manslaughter, and then again in the UK at Maidstone Crown Court in 1988 for 12 years for rape, burglary and ABH.
In 1997 he was sentenced to 13 years in Italy for rape and attempted murder, and was repatriated here in 2004 to serve the rest of his sentence.
Jailing him today, Recorder Nigel Peters QC said: "What's clear is that you are someone who has a history of violent offences and sexual offences and are clearly somebody who is considered at the highest risk end of involvement in offences involving sexual matters and violence."
Durkin, from St John's Wood, north-west London, earlier admitted one count of failure to comply with notification requirements between October 12 and November 14 last year.
A second count of the same offence for failing to notify police of his address was ordered to lie on file.
At first he claimed that someone else called Troy had used his phone, but he was caught sending a text message using that name from a police station after his arrest.
He had a tent at the Finsbury Square site of the Occupy London demonstration, which was also based outside St Paul's Cathedral.
Durkin was given two months to run concurrently for breaching bail conditions while on an electronic tag. Police said he was not at home on two days in April this year.
He was also banned from staying overnight at any protest camp in the UK.
