VATICAN CITY, March 1 (Reuters) - The secret conclave that elected Pope Leo head of the Catholic Church last May was interrupted when one of the 133 cardinals involved was found carrying a cellphone, a massive security breach, a book released on Sunday revealed.
As the clerics were preparing to take their first vote inside the Vatican's Sistine Chapel, which was fitted with jamming equipment to prevent outside communications, security officials picked up the signal of an active mobile connection.
