LAS VEGAS -- The Elvis Presley estate has filed a lawsuit against a Las Vegas casino-hotel, as the King's artifacts are being held as part of an ugly leasing dispute.

Elvis Presley Enterprises is trying to get back hundreds of items it loaned to the much-hyped "Graceland Presents Elvis" attraction at the Westgate Las Vegas Resort and Casino.

The off-Strip property took hold of the items in February when it shut down the attraction after the third-party operator, Exhibit A Circle, said it was quitting.

Westgate confirmed the lawsuit but declined to discuss the case.

Elvis Presley Enterprises didn't immediately provide comment but had previously said that Westgate aggressively seized the valuables without a legitimate legal basis.

The company runs the Graceland attraction in Memphis, Tennessee, and manages many of the official business deals.
