AFTER 105 witnesses and three months of evidence, a drug trial costing $1 million was aborted yesterday when it emerged that jurors had been playing Sudoku since the trial's second week.

In the District Court in Sydney, Judge Peter Zahra discharged the jury after hearing evidence from two accused men, one of their solicitors and the jury forewoman, who admitted that she and four other jurors had been diverting themselves in the jury box by playing the popular numbers game.

More than 20 police gave evidence in the case, in which the two accused faced a common charge of conspiracy to manufacture a commercial quantity of amphetamines. One faced further firearms and drug possession indictments. The prosecution and defence were due to deliver final addresses to the jury this week.
