From newsday:
Bernard Kerik, New York City’s disgraced former police commissioner, went to jail Tuesday after a judge revoked his bail for disclosing sealed trial information that could poison his upcoming corruption trial.
At the end of a hearing before U.S. District Court Judge Stephen Robinson in White Plains, Kerik took off his purple tie, emptied his pockets and removed a ring from his finger, giving his possessions to his lawyer before marshals led him away.
