why was ulysses s grant arrested

Ulysses S. Grant was arrested in 1872 while he was serving as the President of the United States for speeding in his horse-drawn carriage in Washington, D.C. The arrest was made by Officer William H. West of the Metropolitan Police Department, who initially gave Grant a warning for speeding but stopped him again the next day when Grant was speeding once more. Officer West told Grant that although he was the chief of the nation, duty compelled him to place Grant under arrest. Grant paid a $20 bond but did not appear in court, forfeiting the bond. This incident, if it did occur as reported, makes Grant the only U.S. president known to have been arrested while in office. Grant reportedly responded respectfully to the officer and even later complimented him for his fearlessness in enforcing the law. This event highlights Grant's fondness for fast horses and buggy racing and has been noted as a symbol of the rule of law.
