MONTREAL -- The trial of seven alleged Hells Angels members accused of murder and conspiracy after a massive police operation in 2009 has been postponed until Aug. 10.

It was scheduled to start today in Montreal but one of the jurors couldn't participate due to professional reasons.

The trial is the result of a 2009 police operation called SharQc that netted more than 150 people, including 111 suspected members of the Hells Angels biker gang.

Two people charged in the case pleaded guilty Friday to conspiracy to commit murder, bringing the total number of people who have pleaded out to 103.

In May 2011 a judge released 31 of the accused due to unreasonable delays in the court proceedings.

Another two accused, who are anglophone, will have a separate trial, in English, beginning in January.

Eight people wanted in the case are still on the lam and three accused have died since 2009.
