A judge in the United States has revoked the house arrest of President Donald Trump's former campaign chairman, ordering that he be held in jail while awaiting trial.
Paul Manafort was ordered into custody on Friday following new obstruction of justice charges filed by Special Counsel Robert Mueller last week.
Manafort is facing multiple charges of money laundering, bank fraud and illegal lobbying. He was among the first to be indicted by Mueller, who is heading up the main investigation into alleged Russian meddling in the 2016 US presidential elections.
After turning himself in to the FBI in October, Manafort was placed under house arrest on a $10m bond.
Last week, Mueller issued a motion saying that Manafort had contacted witnesses by phone and encrypted text messaging for the purpose of securing "materially false testimony".
It added that such activities amounted to a violation of his bail terms.
"I cannot turn a blind eye," US District Judge Amy Berman Jackson said on Friday. "You've abused the trust placed in you."
