The 37-year-old and 19-year-old suspects were charged Saturday on weapons violations and handling a stolen book.
Authorities say two books were recovered when the men were arrested Friday. The advance copies of the book titled Harry Potter and the Half Blood Prince are being held as evidence.
The sixth installment of the worldwide best-selling series by British author J. K. Rowling is due to be released July 16. The fifth book made publishing history in 2003 when five million copies were sold on the first day.
