A Peruvian judge ordered opposition leader Keiko Fujimori to return to prison for a further 15 months' pre-trial detention Tuesday as part of an investigation into Latin America's sprawling Odebrecht corruption scandal.
Fujimori, 44, who was in court to hear the ruling by Judge Victor Zuniga, was immediately arrested and taken to Chorrillos women's prison in south Lima.
"I impose preventive detention for a period of 15 months," Zuniga told the court in Lima after a hearing that lasted 10 hours.
Fujimori previously spent 13 months in pre-trial detention at the Chorrillos facility before she was released in November, but anti-corruption prosecutors had appealed that decision by the Constitutional Court.
Her lawyer, Giuliana Loza, told reporters: "Obviously, this defense is appealing the ruling."
Once Peru's most popular politician, Fujimori had rejected accusations that she was a flight risk and posed a danger of obstruction to prosecutor Jose Domingo Perez's investigations.
Perez, who was not in court, had requested the judge impose a further 18-month pre-trial detention period, saying there was an increased risk she would flee the country as there was new information against her.
Tuesday's ruling caps a disastrous few days for Fujimori, whose once-powerful Popular Force party was decimated in legislative elections on Sunday, losing dozens of seats in the Congress it had dominated since 2016.
Fujimori is accused of accepting US$1.2 million in illicit party funding from Brazilian construction giant Odebrecht for her unsuccessful 2011 presidential election campaign.
Odebrecht has admitted to paying at least US$29 million to Peruvian officials since 2004, and bribing four former Peruvian presidents.
But the Odebrecht scandal stretches far beyond Peru.
Latin America's largest construction firm has admitted to paying hundreds of millions of dollars in bribes to win juicy contracts in 12 countries.
Fujimori, who twice was narrowly defeated in presidential election runoffs — in 2011 and again in 2016 — has seen her popularity rating plummet during the case though she remains an influential figure in Peruvian politics.
She grew up during her father Alberto Fujimori's deeply divisive decade as president from 1990-2000.
Keiko sided with her father when her mother Susana Higuchi accused Alberto's men of torturing her and divorced him in 1994.
With her mother gone from the political stage, Keiko effectively took over first lady duties at the age of just 19.
Educated in the United States, she married an American, Mark Villanella, with whom she has two daughters.
Villanella undertook a hunger strike outside his wife's prison late last year to press for her release.
She announced in December she was taking a break from politics to prioritise her family.
Alberto Fujimori, now 81, remains in jail for crimes against humanity.
A court held him responsible for massacres of people he said were terrorists in 1991 and 1992, including one incident in which a university professor and nine students were abducted by a death squad and killed.
