Black-cab rapist John Worboys has been moved to a London jail ahead of his release.
The notorious sex offender was transferred over 200 miles from HMP Wakefield in West Yorkshire to HMP Belmarsh, south-east London, the Sun reported.
The majority of attacks carried out by Worboys took place in London.
One victim told the newspaper: “I am genuinely terrified he is going to come after me.
“Why should we think he won’t? He knows where so many of his victims live.”
Since the announcement at the beginning of January that London cabbie Worboys would be freed just nine years after he was imprisoned prompted dismay from victims' groups, politicians and legal experts.
The 60-year-old was jailed indefinitely in 2009, with a minimum term of eight years, for drugging and sexually assaulting women passengers.
Worboys was convicted of 19 offences against 12 victims but has been linked to more than 100 complaints in total.
After the Parole Board's decision was revealed, there were calls for him to be located away from Greater London to reassure terrified victims.
A group of MPs called for an "exclusion zone" to be imposed to ban the former taxi driver from the capital.
It is understood Worboys's release is not imminent and his transfer does not mean he will necessarily be freed into the capital.
Last week Justice Secretary David Gauke stressed that Worboys will not be released until his licence conditions have been finalised, and victims signed up to a contact scheme have had their say on the restrictions.
When he is released, Worboys is expected to spend several months in a probation hostel.
A potential legal challenge by the Government over Worboys's release was ruled out by Mr Gauke last week, but lawyers for two victims have said they intend to pursue the case in the courts.
