Former PR guru Max Clifford has been arrested over fresh sex allegations, it is understood.
Scotland Yard said a 71-year-old man has been arrested under Operation Yewtree – the inquiry set up in the wake of the Jimmy Savile scandal.
Detectives have so far spoken to 17 people as part of the Metropolitan Police’s Yewtree investigation which has been running since October 2012
Scotland Yard would not confirm the identity of the 71-year-old but said: “This is not a new individual to Operation Yewtree. This is not an 18th individual.”
The spokesman said the man has been arrested “under the strand of the investigation we have termed Others”.
He has been interviewed at a police station in Peterborough and inquiries are continuing.
In November, Clifford lost an appeal to have his jail term cut with judges ruling it was “justified and correct”.
Clifford, 71, was jailed in May last year after a seven-week trial in which he was shown to be a manipulative sex offender who had abused a string of young women during his career.
Many of his victims had been teenagers looking for work in show business.
In court he dismissed the women as “fantasists and liars” who were making the allegations in pursuit of compensation.
However, he was found guilty of eight sex attacks on four victims between 1977 and 1984. The judge said he also believed other “supporting witnesses” who had made serious allegations.
He was jailed for eight years.
