CHICAGO -- Joseph J. Scalise, 42, a suspect in a $3.5 million London jewelry store heist, has been ordered extradited to Great Britain.

However, Scalise's attorney, Edward M. Genson, told U.S. Magistrate Olga Jurco Friday he plans to file a series of motions which could delay his client's actual return to England for a year or more.

Scalise and Arthur Rachel, 42, are suspects in the Sept. 11, 1980, holdup of Graff's Jewelers in a fashionable area of London. None of the loot from the robbery, including the famed Marlborough Diamond, worth nearly $1 million, has been recovered.

Extradition documents filed by the British government said the suspects were seen fleeing the store in a rented car. A witness provided police with the car's license number and it was traced to a hotel room Scalise and Rachel had rented.

By the time police got to the hotel, however, the suspects had left on a flight for Chicago. They were arrested as they left the plane at O'Hare International Airport.
