RCMP have accused a Vernon, B.C., lawyer of being involved with organized crime.

Authorities arrested the lawyer Friday morning and charged him with participation in activities of a criminal organization.

They say the lawyer was involved with "The Greeks," an Okanagan-based group that has five members in custody on three homicide charges.

The Greeks are known to have dealings with the Calgary chapter of the Hells Angels and a Kelowna chapter of the Hells Angels, and are suspected of having ties to the UN gang in the Lower Mainland.

William Mastop, 43, is scheduled to appear in court in Vancouver on Monday.
