Detroit Mayor Kwame Kilpatrick, who awaits trial on perjury and other charges, has been ordered to county jail after violating his bond by leaving the country.
Earlier, assistant prosecutor Robert Moran argued Kilpatrick should have told Judge Ronald Giles of a trip to Canada. The mayor, who is required to alert the court to all travel plans, went across the border last month to push the sale of the city's half of the Detroit-Windsor Tunnel.
Kilpatrick apologized to the court for the infraction, but Giles ordered him into custody, saying he was giving the mayor the same treatment as any other criminal defendant.
Kilpatrick's attorneys said they would immediately appeal the ruling.
Earlier Thursday, Kilpatrick waived his right to a preliminary hearing on charges of perjury, misconduct and obstruction of justice that stem from accusations that he and his ex-Chief of Staff Christine Beatty lied about having an intimate relationship and their roles in firing a police official.
Kilpatrick and Beatty denied under oath during a civil trial last year that they had a romantic relationship in 2002 and 2003. Text messages allegedly exchanged between the two in April reveal sexually explicit exchanges and professions of love and promises of marriage.
Kilpatrick and his high-priced team of attorneys have questioned the authenticity of those and other text messages, while fighting battles on several legal and political fronts.
The mayor and Beatty agreed on Thursday to waive their rights to a preliminary hearing, and Giles set a circuit court arraignment date of Aug. 14.
