WASHINGTON (AP) _ Customs Commissioner Raymond W. Kelly is recovering from heart bypass surgery.

The Customs Service said today that doctors at Georgetown University Hospital performed the bypass surgery on June 11, following a medical examination.

A former Marine and New York City police commissioner, the 57-year-old Kelly assumed the helm of the nation's oldest law-enforcement agency last August.

``The prognosis is excellent for a full recovery,'' said a statement from the Customs Service. It added that Kelly is ``recovering quickly.''

Customs official Dennis Murphy said Kelly was released from the hospital Wednesday and stopped by work. Kelly is setting up procedures to work from home, Murphy said, adding that he didn't know how long the commissioner will be recuperating. Sam Banks, Customs' deputy commissioner, will help run day-to-day operations.

``I understand that people who undergo heart bypass surgery usually have more energy when they fully recover,'' Kelly said in a statement. ``I always thought I kept a pretty active pace in my life. I'm anxious to see how much more I can do with added energy.''
