Supreme Court Chief Justice John Roberts has been the victim of credit-card fraud.

On Tuesday, the day of oral arguments over California's same-sex marriage ban, Roberts was forced to pay for his morning Starbucks coffee in cash, the Washington Post first reported.

The chief justice told the cashier someone had gotten hold of his credit card numbers and he had to cancel the card.

A Supreme Court spokeswoman confirmed to the Associated Press that Roberts' account numbers were breached, but provided no other details.

The last reported crime involving a member of the court was in May, when Justice Stephen Breyer's Washington home was burglarized -- just months after he was robbed by a machete-wielding intruder while at his vacation home in the Caribbean.
