Ulysses S. Grant, while serving as President of the United States, was arrested for speeding in 1872. He was caught by a Metropolitan Police officer in Washington, D.C., riding his horse and buggy too fast. Despite being the sitting president, Grant was taken to the police station, paid a $20 bond, and forfeited it by not appearing for trial. This incident makes him the only U.S. president known to have been arrested while in office. The story highlights Grant's love for horses and his somewhat reckless horse-drawn carriage "driving," and it is also noted that he respected the rule of law, commending the officer for doing his duty fearlessly.
Additionally, there were two earlier arrests of Grant in 1866, when he was Army Commanding General, also for speeding on horseback, but these were not while he was president.
