Regina police have arrested 4 more picketing Unifor members at the Co-Op refinery, but the union claims they were doing nothing wrong or illegal and had no blockades set up. Meantime, police in Regina have been ticketing vehicles blocking the entrances and exits to the Co-op Refinery Complex and nearby fueling station   Unifor members have been locked out of the refinery since December 5th, and pensions are at the heart of the dispute.
