Members of the Gang Task Force were used to boost security at the Vancouver Law Courts Thursday as four separate gang cases went ahead with rivals appearing on different floors. Eight members of the uniformed GTF arrived for a bail revocation hearing for accused drug trafficker Sukhveer Dhak. One floor below, a cocaine conspiracy trial continued for Dhak rival Jarrod Bacon. Supt. Doug Kiloh, of the Combined Forces Special Enforcement Unit, said the GTF officers were on hand because "there is clearly unresolved conflict between gangs." "Do we have concern when we bring them together? Yes, and clearly that poses a public safety risk," Kiloh said. "Even at the Bacon trial, there is going to be conflict internally there." Kiloh said that when any case like that of Bacon and coaccused Wayne Scott has wiretaps being played, things can be tense because of what one party says about the other. Earlier this week, a tape was played in court of Scott saying Bacon's parents were aware of his criminal enterprise, and profited from it. "There are a number of security precautions we are taking," Kiloh said of the Bacon-Scott case. Not only were Dhak and Bacon in separate courtrooms Thursday, but the Greeks gang murder case continued in high-security Courtroom 20 a few floors below. And another case, involving men linked to the United Nations gang, was in pre-trial hearings next door to Dhak. Kiloh said CFSEU has several other big cases and that more charges are expected to be laid in coming weeks. "We know we have been pushing Crown hard. We know they have their hands full," he said. "We hope to have more charges in the coming weeks and months in high-profile cases involving gangs and organized crime." And Kiloh said law enforcement will continue to move forward with major gang prosecutions because "it reduces the threat of public safety issues." Just last month, GTF head officer Supt. Tom McCluskie issued an extraordinary public warning that anyone associating with Dhak or those in the affiliated Duhre group could be at risk because of escalating gang tensions. The Dhaks, Duhres and some members of the UN gang are aligned against an opposing group consisting of some Hells Angels, Red Scorpions and the Independent Soldiers. On Sept. 16, Dhak associate Jujhar Singh Khun-Khun was shot several times in a targeted Surrey shooting that police say may have been in retaliation for the Aug. 14 attack in Kelowna that left Red Scorpion Jonathan Bacon dead and Hells Angel Larry Amero and Independent Soldier James Riach wounded. Dhak was originally charged in October 2008 with production of a controlled substance, possession for the purpose of trafficking and conspiracy to commit indictable offence. He is due to go to trial in that case next April. But he was arrested Sept. 18 for allegedly driving while prohibited related to an incident on July 30, 2011. He is also before the courts on another breach allegation related to a Kelowna incident in March 2011 and was charged in December 2010 with one count of counselling to commit the indictable offence of aggravated assault. Justice Brenda Brown reserved her decision on Dhak's bail until next Wednesday. Dhak, dressed in red prison garb, whispered through Plexiglas to his girlfriend at the morning break Thursday. Police sat in the front row, several seats away from Dhak's mother, sister and girlfriend. Details of submissions and arguments at the two-hour hearing are covered by a publication ban. Kiloh said top police officers from around the Lower Mainland met Thursday to discuss the level of gang tensions. He said the situation is very fluid, with unresolved conflicts between some, and others making new associations that police are trying to assess.
