West Vancouver man with ties to several criminal gangs vanished Sept. 5, only two days before he was due to be sentenced for a drug trafficking conviction. Police say Omid Bayani, 36, appeared to be headed to one of the North Shore gyms he frequented when he left his home that afternoon, but hasn't been seen since. A senior figure in the UN Gang, Bayani arranged to sell 600 litres of the date rape drug GHB to a Hells Angels chapter in Toronto in 2007. But the operation was infiltrated by the Ontario Provincial Police and Bayani was convicted of trafficking. The Crown was asking for a sentence of eight to nine years in prison, and Bayani was supposed to be in court to learn his fate Sept. 7. Bayani was convicted of a series of armed robberies in Alberta in the 1990s and has also faced a variety of drugs, weapons and assault charges in B.C. over the past decade. According to the West Vancouver police, Bayani is Middle Eastern, six feet tall and weighs 240 pounds. He has short, black hair, brown eyes and a goatee, but no moustache. He was last seen wearing a grey-and-white Under Armour shirt, blue Under Armour shorts and running shoes
