Manafort's detention order at a U.S. District Court hearing in Washington came a week after he was charged in a new indictment filed by Mueller. The indictment accuses Manafort and a Russian associate, Konstantin Kilimnik, of conspiring to influence the possible testimony of two people.
Manafort had been under house arrest since October when he was first hit with what became a series of criminal indictments related to his consulting work for pro-Russian politicians in Ukraine.
"I cannot turn a blind eye" to the ways Manafort has "abused the trust" of the court, Judge Amy Berman Jackson said as she yanked his bail and ordered him locked up pending his upcoming two federal criminal trials.
"This is not middle school. I can't take his cellphone," Jackson said as she rejected a suggestion by Manafort lawyer Richard Westling that she only modify his bail by barring him from contacting potential witnesses.
Jackson said that although there is "no evidence of even a threat of harm to any person" by Manafort, the harm from new charges "is harm to the administration of justice" and "to the integrity of the system."
