MONTREAL -- Twenty-seven outlaw bikers who were rounded up in a vast police operation in 2009 have pleaded guilty in Quebec to reduced charges of conspiracy to commit murder.

The accused, who are all members of the Hells Angels or gang sympathizers, agreed to enter the plea today after making a deal with the Crown.

Jean-Pascal Boucher, a spokesman for the director of criminal and penal prosecutions, said other charges against the accused -- including murder -- have been dropped.

On Wednesday, two other members of the Hells Angels pleaded guilty to conspiracy to murder charges and had further proceedings against them stopped.

They each face sentences of 15 years in prison.

In April 2009, 156 Hells Angels and sympathizers were rounded up in a massive police operation said to have dealt a severe blow to the gang.
