why was ulysses grant arrested

Ulysses S. Grant was arrested for speeding with his horse-drawn carriage in Washington, D.C. in 1872 while serving as the President of the United States. Police officer William H. West, who was African American and a Civil War veteran, stopped Grant for racing his buggy and after a warning the day before, arrested him for speeding the next day. Grant paid a $20 bond but did not show up for trial, forfeiting the bond. This arrest made Grant the only U.S. president known to have been arrested while in office. The incident symbolized the rule of law, with Grant reportedly respecting the officer's duty despite his high office.
