An auction of tragic artist Jean-Michel Basquiat's works has been shut down over concerns some of the items are fakes.

Christie’s auction house bosses had scheduled the online sale for Monday (17Mar14), but the event has been scrapped following a $1 million (Gbp625,000) lawsuit from the late artist’s estate.

The Basquiat pieces come from the collection of Alexis Adler, who shared a home with the artist.

A statement from an auction house spokesperson reads: "Our goal is to allow time for all parties involved to reach an equivalent level of confidence in the validity of these items, so that the sale may resume at a later date."
