LONDON (AP) _ A tie pin, a photograph and pens were among the items reportedly stolen from Buckingham Palace, a newspaper reported Sunday.

A spokeswoman for the Metropolitan Police, speaking on customary condition of anonymity, confirmed Saturday night that items of ``intrinsic value'' were thought to have been taken from an office within the palace.

She would not say when the theft occurred, what was taken or whose office was raided.

But the Sunday Times newspaper reported that items including a signed photograph and an Olympic tie pin belonging to Princess Anne, the daughter of Queen Elizabeth II, were stolen from her private office.

Pens the princess gives away on official visits also were stolen, the newspaper quoted police as saying.

``The items were of no personal or sentimental value,'' said the police spokeswoman, adding that ``At no time was the security of any members of the royal family compromised.''

A Buckingham Palace spokeswoman declined to comment on the incident.
