The body of Mr Falconio has never been found

Australian prosecutors want it taken off shelves because of a question which allegedly links Bradley Murdoch, 45, to Mr Falconio's girlfriend Joanne Lees.

They fear games on sale in the Northern Territory breach a court suppression order covering forensic evidence.

Mr Murdoch denies shooting Mr Falconio and abducting Ms Lees in July 2001.

The couple, from Huddersfield, West Yorkshire, were allegedly ambushed as they drove along a deserted highway near Alice Springs.

We will be trying to contact them to ensure the game is not distributed in the Northern Territory Jane Munday, prosecution spokeswoman

She said she was bound, gagged and bundled into a pick-up before escaping.

Mr Falconio's body has never been found.

The committal hearing to decide whether Mr Murdoch, of Broome, Western Australia, should stand trial for murder resumes in Darwin on 9 August.

In May, magistrates issued a court order preventing the media in the Northern Territory from reporting a number of issues, including key forensic evidence.

The Director of Public Prosecutions, Rex Wild, told BBC News Online he believed the makers of Trivial Pursuit were in breach of that order.

Question 'dangerous'

He confirmed a question included in the latest Australian version of the game presents as fact key evidence which is yet to be proven in court.

Spokeswoman for the Director of Public Prosecutions, Jane Munday, said it appeared the game's makers, Hasbro, were unaware of the court order.

"We will be trying to contact them [Hasbro] to ensure the game is not distributed in the Northern Territory," she said.

"It is dangerous to use questions on a matter before the courts in games such as this."

No one at Hasbro was available for comment.
