The RCMP and Quebec provincial police say the arrests of 156 Hells Angels and their associates were the culmination of more than 80 investigations going back to 1995.

Officials from the two police forces met reporters in Montreal today to discuss Operation SharQc 2009, the acronym for Strategy Hells Angels Region of Quebec.

Police also seized five Hells Angels bunkers throughout the province Wednesday and claim they shut down the biker gang's East Coast operation.

The accused face charges including first-degree murder, conspiracy to commit murder and gangsterism.

The alleged offences go back to 1992 when, according to police, the biker gang was involved in drug trafficking and gangsterism.

But most of the murder charges are related to Quebec's biker war between 1994 and 2002.
