Black cab rapist John Worboys has been transferred from Belmarsh Prison following outage over his move to a London jail.
The serial sex offender is understood to have returned to HMP Wakefield in West Yorkshire.
The Prison Service faced a backlash in January after Worboys, 60, was transferred to a prison in the city where he committed his crimes.
It comes amid a legal challenge over his imminent release on parole.
Worboys’ return to HMP Wakefield emerged as a lawyer said she had passed details of fresh allegations made by five women to police.
Harriet Wistrich told the Sunday Mirror that two further women, whose cases were reported to police but not prosecuted as part of his trial, have asked for their allegations to be reconsidered.
Worboys was jailed indefinitely in 2009, with a minimum term of eight years, for drugging and sexually assaulting women passengers.
A Parole Board decision that he should be freed on licence after spending less than a decade behind bars has been widely criticised by his victims and politicians.
He became known as the black cab rapist after attacking victims in his Hackney carriage.
The predator was convicted of 19 offences against 12 victims, but has been linked to more than 100 complaints in total.
A High Court judge has ordered a temporary bar on Worboys’ release after considering an urgent application by two of his victims.
The women, supported by London Mayor Sadiq Khan, applied for a “stay” on his release “pending determination of the claim for judicial review or further order”.
A hearing at the High Court in London is now expected between 6 and 8 February, but a date has yet to be confirmed.
