A Banksy mural painted on the only remaining piece of a bombed out house in Gaza could be reunited with the homeless owner who claims he was duped into selling it for just $200. Gaza police have seized the work 'under a court order' from Bilal Khaled, who is accused of buying the piece painted on a door belonging to the Darduna family without telling them its real value. The now homeless family in the impoverished Islamist-run Palestinian enclave says they were 'tricked' into parting with the valuable collector's item by the world famous street artist.

It is now being held at Khan Yunis public library . The mural painted on the Darduna family's door (left) and the doorway of the ruined house after it was sold . At the end of February, the artist, who chooses to remain anonymous, released an online video showing three works he painted on the walls of Gaza homes destroyed in Israeli air strikes. The disputed graffiti shows Greek goddess Niobe weeping on a metal doorway which was all that remained standing of the Darduna family home. Khaled said it 'will be stored at Khan Yunis public library until this issue is resolved'. Rabie Darduna confirmed this to AFP, adding that the family 'has filed a complaint against Bilal Khaled for fraud and to demand justice in retrieving the graffiti'. Khaled countered: 'I'm going to exercise my rights over this graffiti because I have the paperwork to prove that I own it.' The elusive Banksy produced the artwork during a secret visit to Gaza that was blasted in a summer war last year between Israel and the Hamas movement that runs the territory. It is now the focus of an increasingly bitter dispute between the Dardunas and Khaled. Rabieh Darduna, 33, earlier told AFP he had been approached by a young man calling himself Bilal Khaled and claiming to be a news agency photographer and journalist.

A photographer takes a picture of the mural. The man who bought it claims he has paperwork to prove he owns it, but the Darduna family say they feel cheated by the sale . 'He said it was his agency that had painted the graffiti on the door and other doors, and that they now wanted to recover them,' Darduna said. 'He gave me 700 shekels (around $200) and went off with the door.' Darduna said he later felt cheated for letting the door go for so little when collectors have paid more than a million dollars for a Banksy. The artist's works were seen as a damning critique of Israel's bombardment of Gaza as it battled Hamas, destroying or damaging more than 100,000 homes and killing nearly 2,200 Palestinians, most of them civilians. Banksy's murals also include a giant cat painted on the last remaining wall of a Gaza home playing with a ball of twisted metal. The artist's online video about his trip to Gaza was entitled 'Make this the year YOU discover a new destination'. Banksy is believed to have started out as a graffiti artist in London, although his identity remains shrouded in mystery. His murals have been chiselled out of walls and sold for large sums in the past.
